Smith Babbitt is in the prime of his life: he's only 25 years into his 89-year lifespan. He knows this because of Timmy®, the mysterious app that can tell you with infallible accuracy how old you will be when you die. Smith still has 64 years to go. But lately he's been in a rut, and his long lifespan is starting to feel like a sentence. Possible salvation arrives in the form of Mavis Pead, a co-worker at Smith's demoralizing job. Smith is infatuated, despite the age difference: Mavis has just entered the last of her 43 years. She's a "zero" - the most shunned demographic in society. When a careless act leads to their boss's apparent death before his time, Smith and Mavis are thrown together in an intrigue that could call Timmy®'s infallibility into question. Mavis might not be so old after all - nor Smith so young. A laugh-out-loud sendup of a technologically dependent culture, Zero is also a tender love story and a big-hearted reflection on the true meaning of age. A story that asks the question, What do we do with the time we're given, whether we know how long we have...or we don't?
