Every Day by David Levithan: This is a love story about A, a teen who wakes up every morning in a different body, living a different life. There's never any warning about where it will be or who it will be. A has made peace with that, even established guidelines by which to live: Never get too attached. Avoid being noticed. Do not interfere.
It's all fine until the morning A wakes up in the body of Justin and meets Justin's girlfriend, Rhiannon. From that moment, the rules by which A has been living no longer apply. Because, finally, A has found someone he wants to be with. Day in. Day out. Day after day.

What's left of me by Kat Zhang: Eva and Addie started out the same way as everyone else--two souls woven together in one body, taking turn controlling their movements as they learned how to walk, how to sing, how to dance. But, as they grew, so did the worried whispers. Why aren't they settling? Why isn't one of them fading? The doctors ran tests, the neighbors shied away and their parents begged for more time. Finally, Addie was pronounced healthy and Eva was declared gone. Except she wasn't...
Unwind by Neal Shusterman: In America after the Second Civil war, the Pro-Choice and Pro-Life armies came to an agreement: The Bill of Life states that human life may not be touched from the moment of conception until a child reaches the age of thirteen. Between the ages of thirteen and eighteen, however, a parent may choose to retroactively get rid of a child through a process called "unwinding." Unwinding ensures that the child's life doesn't "technically" end by transplanting all the organs in the child's body to various recipients. Now a common and accepted practice in society, troublesome or unwanted teens are able to easily be unwound.

A Monster Calls by Patrick Ness: At seven minutes past midnight, thirteen year old Conor wakes to find a monster outside his bedroom window. But it isn't the monster Conor's been expecting--he's been expecting the one from his nightmare, the nightmare he's had every night since his mother started her treatments. The monster in his backyard is different. It's ancient. It's wild. And it wants something from Conor. Something terrible and dangerous. It wants the truth.
To me, most story premises are not this unique. In fact, these were the only four I could come up with. Do you know any others? And which concept here catches your attention the fastest and makes you want to read the book?
