Book Spotlight: Since You've Been Gone by Morgan Matson

The Pre-Sloane Emily didn't go to parties, she barely talked to guys, she didn't do anything crazy. Enter Sloane, social tornado and the best kind of best friend—the one who yanks you out of your shell. But right before what should have been an epic summer, Sloane just... disappears. No note. No calls. No texts. No Sloane. There’s just a random to-do list. On it, thirteen Sloane-selected-definitely-bizarre-tasks that Emily would never try... unless they could lead back to her best friend. Apple Picking at Night? Ok, easy enough. Dance until Dawn? Sure. Why not? Kiss a Stranger? Wait... what? Emily just wants her best friend back, will doing everything on the list make that possible?
