Paisley has a bucket list. After all, she's going to die in three months. What she expects is for her little excursions to be fun-filled and light-hearted, but what she doesn't expect is to have one thing on her bucket list that can only be achieved by bringing along badass Jude Andrews, who's got some secrets of his own. Now that Jude Andrews is tagging along with Paisley while she sets out to complete her bucket list, she learns he's giving her reasons to want to live as long as possible.

Ellie Sandberg would love to reinvent herself. When she earns a spot at an elite boarding school for young inventors, it seems like the perfect opportunity: A summer away from home, away from her overprotective parents, and away from the hopeless crush who rejected her in the final weeks of school. But no one at the Winthrop Academy Summer Maker Program is exactly as they seem-least of all the charming but mysterious Maddox Cruz. Maddox and his group members are working on a new and improved version of InstaLove, an augmented-reality app invented by a former program attendee, and Ellie soon finds herself invited to join their project. But InstaLove has a history of glitches. Weird little accidents... injuries... users wandering into places they were never meant to go... When a fellow group member goes missing, the tech trail for the crime leads back to InstaLove-and to Ellie. With no one else to trust, Ellie must race to uncover the truth and clear her name...or she might be the next to disappear.
