THE EXACT LOCATION OF HOME

Following the precise coordinates of geocaching doesn’t yield the treasure Kirby Zagonski Jr. seeks: his missing father.

Geeky eighth-grader Kirby can’t understand why his mother won’t call his dad after their generous landlady dies and they’re evicted for nonpayment of rent. Though his parents have been divorced for several years and his father, a wealthy developer, has been unreliable, Kirby is sure he could help. Instead he and his mother move to the Community Hospitality Center, a place “for the poor. The unfortunate. The homeless.” Suddenly A-student Kirby doesn’t have a quiet place to do his schoolwork or even a working pencil. They share a “family room” with a mother and young son fleeing abuse. Trying to hide this from his best friends, Gianna and Ruby, is a struggle, especially as they spend after-school hours together. The girls help him look for the geocaches visited by “Senior Searcher,” a geocacher Kirby is sure is his father. There are ordinary eighth-grade complications in this contemporary friendship tale, too; Gianna just might be a girlfriend, and there’s a dance coming up. Kirby’s first-person voice is authentic, his friends believable, and the adults both sometimes helpful and sometimes unthinkingly cruel. The setting is the largely white state of Vermont, but the circumstances could be anywhere.

Middle school worries and social issues skillfully woven into a moving, hopeful, STEM-related tale.
