Johnny Merrimon, the central figure in John Hart's The Last Child, is a lineal descendant and spiritual soul mate of Huck Finn and Holden Caulfield. Like them, this 13-year-old survivor is resilient, endlessly resourceful and determined to do the right thing in a world that settles for moral shortcuts.

Johnny's self-imposed mission is to find his twin sister, Alyssa, who went missing a year earlier, presumably kidnapped. Her disappearance has shredded his once idyllic family. Now his father is also gone, driven away by guilt—so Johnny's mother supposes—for having failed to pick up Alyssa when he was supposed to. Bereft by this double loss, Johnny's ethereally beautiful mother, Katherine, has fallen into drugs, alcohol and the brutal arms of her former suitor, Ken Holloway, one of the richest men in (mythical) Raven County, North Carolina, where the narrative unfolds.

Police detective Clyde Hunt is just as obsessed as Johnny with finding Alyssa. His single-minded pursuit of the case has already cost him his wife and is threatening to snap his already frayed ties to his son. To complicate matters, he is becoming increasingly attracted to Katherine. Reduced to a summary, the story sounds like a soap opera. But it's not. Here, the interior struggles far outweigh the interpersonal encounters.

Constitutionally a loner, Johnny resorts to every device he can think of—from Christian prayer to Indian rituals to door-to-door canvassing—in his unrelenting search for his sister. At the same time, he's scheming feverishly to protect his mother. He becomes a footloose avenger, a truth-seeking creature of the night, fearful only of failing those he loves. If, like Huck Finn, he risks going to hell for doing his duty, then so be it.

Hart knows how sensitive boys feel and think behind those tough, smirking masks and with what ferocity they cling to their causes. Johnny is innocence and experience in perfect balance.

When 12-year-old Alyssa Merrimon disappeared a year ago, her family fell apart. Her twin brother, Johnny, became obsessed with trying to find her, their father took off, not to be heard from again, and their mother sank into a world of drugs and booze, helped along by an abusive, wealthy boyfriend. Det. Clive Hunt is also obsessed, both with finding Alyssa and with her mother, and his preoccupation costs him his marriage and jeopardizes his job. But this is Johnny's story and his quest to find the sister he lost. Taking his mother's car while she's passed out and occasionally taking along his best friend, Jack, Johnny spies and keeps meticulous records on the townsfolk of small Raven County, NC. The world is a dark place when seen through his eyes, and Johnny is an unforgettable character in this finely drawn yet disturbing thriller. With his best novel yet, the Edgar Award-winning Hart (Down River) firmly cements his place alongside the greats of the genre. Highly recommended for all public libraries.

A year after 12-year-old Alyssa Merrimon disappeared on her way home from the library in an unnamed rural North Carolina town, her twin brother, Johnny, continues to search the town, street by street, even visiting the homes of known sex offenders, in this chilling novel from Edgar-winner Hart (Down River). Det. Clyde Hunt, the lead cop on Alyssa's case, keeps a watchful eye on Johnny and his mother, who has deteriorated since Alyssa's abduction and her husband's departure soon afterward. When a second girl is snatched, Johnny is even more determined to find his sister, convinced that the perpetrator is the same person who took Alyssa. But what he unearths is more sinister than anyone imagined, sending shock waves through the community and putting Johnny's own life in danger. Despite a tendency to dip into melodrama, Hart spins an impressively layered tale of broken families and secrets that can kill. 175,000 first printing; author tour. (May)

Adult/High School—Thirteen-year-old Johnny searches for his twin sister who disappeared a year earlier while also mourning the loss of his guilt-ridden father and trying to cope with his mother's abusive boyfriend. Parallel to the rapidly unfolding events is an intriguing and adrenaline-rich mystery that unfolds through Clyde Hunt, lead police detective in Johnny's North Carolina town. Hart develops both characters fully and credibly and brings to life a cast of supporting actors that includes Johnny's depressed and drugged mother and his best friend. The climate and history of the place offer both clues and a well-delineated setting for the plot, giving readers a "you are there" sensibility and an appreciation for how the past creates the present in both evil and good ways. Hart's writing is rich and flowing. Teens looking for adventure, and a story in which a kid shows himself to be smarter than most of the adults around him, will find this novel wholly satisfying.—Francisca Goldsmith, Halifax Public Libraries, Nova Scotia
