Many of my favourite authors have started writing YA series. Harlan Coben is one of them. He first introduced us to Myron Bolitar's nephew Mickey Bolitar in Live Wire. Mickey's first book on his own series was Shelter. (I quite enjoyed it) And the next book Seconds Away is newly released.
From the publisher Penguin Books:
"When tragedy strikes close to home, Mickey Bolitar and his loyal new friends—sharp-witted Ema and the adorkably charming Spoon—find themselves at the center of a terrifying mystery involving the shooting of their friend Rachel. Now, not only does Mickey have to continue his quest to uncover the truth about the Abeona Shelter, the Butcher of Lodz and the mysterious death of his father, he needs to figure out who shot Rachel—no matter what it takes.
