This first novel's promising premise-Carey (a New York Times science reporter) uses mathematical equations and theorems as clues to a mystery-sinks under the weight of burdensome plotting and characters' hypothesizing. Spearheading the sleuthing are Di and Tom, seventh-grade misfits determined to find Mrs. Clarke, a kindly neighbor who helps them with their math homework, after she vanishes. The kids live in a bleak trailer park located beside an underground nuclear plant, made all the more unsavory by the nearby dump, Mt. Trashmore, "an entire rotting universe, reeking like sugary vomit." Deciphering notations left by Mrs. Clarke, the kids draw a map that leads them to underground tunnels, which they suspect hold the key to the woman's disappearance. The maps-simple diagrams that grow as information is uncovered-help elucidate their discoveries, yet digressions and a steady stream of data ("The Trashmore entrance was eight hundred yards above the x-axis. But the tunnel angled inward one hundred yards for every four hundred it moved downward") may dampen interest in what feels like an extended, if adventurous, story problem. Ages 10-up.

In Folsom Adjacent, a trailer park town that is not even important enough to have its own name, Di and Tom notice people are disappearing. They don't think much of it until their math tutor, Mrs. Clarke, is taken, too, leaving behind a strange equation: 3 + 4 = 5. The kids take the clue and run. Soon they realize they are being pursued by agents from the Folsom nuclear power plant. The two friends are pulled into a dangerous mystery made up of mathematical clues left by their tutor and begin enlisting other kids in town to help them. With the fate of their whole town at stake, can they brave the tunnels under their trailer park and find a way to save Mrs. Clarke? It is refreshing to see a book for this age range that takes place somewhere outside a major city or a middle class suburb, though a little too much time is spent on the school lives of Di and Tom when not much of the plot takes place there. While kids who already enjoy math might like being able to figure out the puzzles throughout the novel, the constant stopping of the plot for graphs and circles could put some readers off.

Preteen outsiders Tom Jones and Lady Di do not exactly fit in. Quiet Tom sees the world in strange colors and patterns whereas overweight Di constantly twirls her wrist when she is nervous. The friends think their biggest problem will be starting middle school in the fall and having to face the bullies and gangs that await them until their elderly friend Mrs. Clarke disappears. Why was there blood in Mrs. Clarke's abandoned trailer? Were the straws Mrs. Clarke left behind clues? As Di and Tom unravel the mystery, they discover their strange but sleepy little town of Folsom Adjacent (actually just a trailer park named after the nuclear plant where most of the adults work) hides many sinister secrets in the terrifying tunnels under the power plant. Di and Tom take on the corporate conspiracy that threatens their town with the help of other Adjacent misfits and Mrs. Clarke's enigmatic mathematical clues. Successfully working in the concepts of pi and the Pythagorean theorem into an adventure story is no easy task, but for the most part Carey succeeds because of his lively and unique writing. Readers can skim over the math puzzles and still follow the action. Adjacent is a sad and weird but fascinating place populated by strange yet completely believable and compelling characters who bravely face both inner and outer demons. Reviewer: Amy Luedtke

Gr 6–8—This clever and unusual mystery is tailor made for young mathematicians. Lady Di and Tom Jones live in Folsom Adjacent, a godforsaken trailer park named after the giant power plant that shares the small coastal island. When people start vanishing from this nuclear nowhere, the two 11-year-olds investigate, using mathematical cues left behind by their missing math tutor. Equations, right triangles, pi, coordinates, and slope help the kids and some of their similarly outcast friends negotiate a massive maze of underground tunnels to access the plant and discover a nefarious scheme that will destroy the island. Carey is particularly adept at creating setting: the landscape is raw, desolate, and nearly apocalyptic. Math moves the plot along, at times at the expense of character development. Replete with diagrams, charts, and illustrated problems, the book will appeal especially to kids who love geometry, but it will also reel in fans of less numbers-centric books such as Eric Berlin's The Puzzling World of Winston Breen (Putnam, 2007) or Ellen Raskin's The Westing Game (Puffin, 1992).—Connie Tyrrell Burns, Mahoney Middle School, South Portland, ME
On the circular island where the Folsom Nuclear Plant is located, there sits a trailer park called Folsom Adjacent; not surprisingly, many of its colorfully boring residents work at the plant. Eleven-year-olds Diaphanta (Lady Di) and Tamir al-Khwarizmi (Tom Jones) get their wish for something exciting to happen when adults start vanishing from the population. The police department of nearby Crotona doesn't seem to care much, and most adults in Adjacent either work too much or drink too much or both. When their best adult friend Mrs. Clarke vanishes, she seems to leave behind a clue in a math puzzle, which leads to another clue in a math puzzle, and suddenly Di and Tom are taking on Folsom officials to foil an evil plot with a little help from their . . . acquaintances. Carey's debut is a brainteaser of a mystery full of quirky characters. Di and Tom are plucky outsiders with low self-esteem and overactive imaginations. By the third or fourth puzzle (they get progressively more difficult) things get a bit mathematically dense, but even reluctant mathematicians will enjoy this inheritor of The Westing Game.
