If I Stay by Gayle Forman:

Just listen,’ Adam says with a voice that sounds like shrapnel. I open my eyes wide now. I sit up as much as I can. And I listen.‘Stay,’ he says.

Everybody has to make choices.Some might break you.For seventeen-year-old Mia, surrounded by a wonderful family, friends and a gorgeous boyfriend decisions might seem tough, but they’re all about a future full of music and love, a future that’s brimming with hope. But life can change in an instant. A cold February morning . . . a snowy road . . . and suddenly all of Mia’s choices are gone. Except one.
As alone as she’ll ever be, Mia must make the most difficult choice of all.

Gripping, heartrending and ultimately life-affirming, If I Stay will make you appreciate all that you have, all that you’ve lost – and all that might be.

Before I Fall by Lauren Oliver:

They say ‘live every day as if it’s your last’ – but you never actually think it’s going to be. At least I didn’t.
The thing is, you don’t get to know when it happens. You don’t remember to tell your family that you love them or – in my case – remember to say goodbye to them at all.
But what if, like me, you could live your last day over and over again? Could you make it perfect? If your whole life flashed before your eyes, would you have no regrets? Or are there some things you’d want to change…?
