There's something about Truman Alexander that Skyler Finch finds incredibly annoying. Actually, several things: his voice (grating), his arrogance (total know-it-all), his debate-team obsession (eyeroll), and his preppy vibe (does he iron his shorts?). She does her best to avoid him and focus on the important stuff: friends, school, and her boyfriend, Eli. His promposal was perfect--just like he is--and the future is looking bright. Or is it?

For some unexplainable reason, Skylar's phone is sending her notifications from the future . . . a future in which, to her horror, she appears to be with Truman. As in, romantically. As in, Skyler cannot let that happen.

But trying to change the future means messing up the present, and what Skyler sees keeps shifting. Classmates disappear and reappear, swap partners and futures. Turns out there are no actions without reactions, and life doesn't come with a road map. But sometimes the wandering leads you exactly where you need to be, and people--like glitchy phones--are full of surprises.
