SHELTER was an exciting mystery with charismatic characters and a well-developed plot. Mickey Bolitar is living with his uncle Myron in New Jersey. His father died in a car accident and his mother became a drug addict. Myron and his father were estranged and Mickey is not warming to his new uncle. Mickey is only a sophomore in high school but is very mature for his age. He and his parents traveled the world working for a non-profit organization. They came back to the US to make a more settled home for Mickey for his last three years of high school. Mickey is a talented basketball star, much like his uncle Myron.Now that Mickey is living with Myron while his mother is in rehab, he is starting school in the town where his father and uncle were raised. He makes friends with Ashley, who is also a new kid, and is then distressed when after three weeks of school she disappears. He also makes friends with Ema who is an overweight, goth girl who is one of the school's social outcasts and Spoon who is a unique character and who adds some humor to the story with his non sequitur trivia. Of course, Spoon also has access to school keys since his father is a janitor there. Together the three investigate Ashley's disappearance and learn about the white slavery trade, Nazi war crimes, and what Mickey's parents were really doing in their time overseas. I liked all the characters and especially liked Mickey. I look forward to reading the next book in the Mickey Bolitar series--especially since this one left some tantalizing questions that need answers.
