Books The Twilight saga are a series of young adult vampire novels written by Stephenie Meyer. They tell the story of Isabella Swan when she moves to the small rainy town of Forks and falls in love with a vampire named Edward Cullen.
Twilight

When Isabella Swan moves to the gloomy town of Fork and meets the mysterious, alluring Edward Cullen, her life takes a thrilling and terrifying turn. With his porcelain skin, golden eyes, mesmerizing voice, and supernatural gifts, Edward is both irresistible and impenetrable. Up until now, he has managed to keep his true identity hidden, but Bella is determined to uncover his dark secret.
What Bella doesn't realize is the closer she gets to him, the more she is putting herself and those around her at risk. And, it might be too late to turn back....
"About three things I was absolutely positive.
First, Edward was a vampire.
Second, there was a part of him - and I didn't know how dominant that part might be - that thirsted for my blood.
And third, I was unconditionally and irrevocably in love with him."
"I'd never given much thought to how I would die - I'd had reason enough in the last few months - but even if I had, I would no have imagined it like this.... Surely it was a good way to die, in the place of something else, someone I loved. Noble, even. That ought to count for something."
New Moon

For Bella Swan, there is one thing more important than life itself: Edward Cullen. But being in love with a vampire is even more dangerous that Bella ever could have imagined. Edward has already rescued Bella from the clutches of one evil vampire, but now, as their daring relationship threatens all that is near and dear to them, they realize their troubles may be just beginning....
"I knew we were both in mortal danger.
Still, in that instant, I felt well. Whole.
I could feel my heart racing in my chest,
the blood pulsing hot and fast through my veins again.
My lungs filled deep with the sweet scent that came off his skin.
It was like there had never been any hole in my chest.
I was perfect - not healed, but as if
there had never been a wound in the first place."
"I felt like I was trapped in one of those terrifying nightmares, the one where you have to run, run till your lungs burst, but you can't make your body move fast enough.... But this was no dream, and, unlike the nightmare, I wasn't running for my life; I was racing to save something infinitely more precious. My own life meant little to me today.
Eclipse

As Seattle is ravaged by a string of mysterious killings and a malicious vampire continues her quest for revenge, Bella once again finds herself surrounded by danger. In the midst of it all, she is forced to choose between her love for Edward and her friendship with Jacob - knowing that her decision has the potention to ignite the ageless struggle between vampire and werewolf. With her graduation quickly approaching, Bella has one more decision to make: life or death. But which is which?
"In the dead silence,
all the details suddenly fell into place for me
with a burst of intuition.
Something Edward didn't want me to know.
Something Jacob wouldn't have kept from me.
Something that had the Cullens and the wolved both in the woods, moving in hazardous proximity to each other....
Something I'd been waiting for anyway.
Something I knew would happen again,
as much as I might wish it never would.
It was never going to end, was it?"
""Bella?"
Edward's soft voice came from behind me. I turned to see him spring lightly up the porch steps, his hair windblown from running. He pulled me into his arms at once, just like he had in the parking lot, and kissed me again. This kiss frightened me. There was too much tension, too strong an edge to the way his lips crushed mine - like he was afraid we had only so much time left to us.
Breaking Dawn

To be irrevocably in love with a vampire is both fantasy and nightmare woven into a dangerously heightened reality for Bella Swan. Pulled in one direction by her intense passion for Edward Cullen, and in another by her profound connection to werewolf Jacob Black, she has endured a tumultuos year of temptation, loss, and strife to reach the ultimate turning point. Her imminent choice to either join the dark but seductive world of immortals or pursue a fully human life has become the thread from which the fate of two tribes hangs.
Now that Bella has made her decision, a startling chain of unprecedented events is about to unfold with potentially devestating and unfathomable consequences. Just when the frayed strands of Bella's life-first discovered in Twilight, then scattered and torn in New Moon and Eclipse-seem ready to heal and knit together, could they be destroyed ... forever?
"Don't be afraid," I murmured.
"We belong together."
I was abruptly overwhelmed by the truth of my own words.
This moment was so perfect, so right,
there was no way to doubt it.
His arms wrapped around me,
holding me against him....
It felt like every nerve ending in my body
was a live wire.
"Forever," he agreed. When you loved the one who was killing you, it left you no options. How could you run, how could you fight, when doing so would hurt that beloved one? If your life was all you had to give, how could you not give it? If it was someone you truely loved?
The Host

Melanie Stryder refuses to fade away.
Our world has been invaded by an unseen enemy. Humans become hosts for these invaders, their minds taken over while their bodies remain intact and continue their lives apparently unchanged. Most of humanity has succumbed.
When Melanie, one of the few remaining "wild" humans, is captured, she is certain it is her end. Wanderer, the invading "soul" who has been given Melanie's body, was warned about the challenges of living inside a human: the overwhelming emotions, the glut of senses, the too-vivid memories. But there was one difficulty Wanderer didn't expect: the former tenant of her body refusing to relinquish possession of her mind.
Wanderer probes Melanie's thoughts, hoping to discover the whereabouts of the remaining human resistance. Instead, Melanie fills Wanderer's mind with visions of the man Melanie loves - Jared, a human who still lives in hiding. Unable to seperate herself from her body's desires, Wanderer begins to yearn for a man she has been tasked with exposing. When outside forces make Wanderer and Melanie unwilling allies, they set off on a dangerous and uncertain search for the man they both love.
