Ridley Pearson is the author of over fifty novels, including Peter and the Starcatchers (co-written with Dave Barry) and the Kingdom Keepers and Lock and Key series. He has also written two dozen crime novels, including Probable Cause, Beyond Recognition, Killer Weekend, The Risk Agent, and The Red Room. With The Initiation (HarperCollins), Pearson brings us the riveting first tale of the Lock and Key trilogy about the origins of the rivalry between literature’s most famous enemies—Sherlock Holmes and James Moriarty, told from the perspective of James’s little sister, Moria. Before James grew up to be a remorseless villain, he was a curious boy from Boston, with a penchant for trouble and an acid tongue. Thrown into a boarding school against his wishes, James winds up rooming with an unlikely companion: a lanky British know-it-all named Sherlock Holmes (“Lock” to his friends). An heirloom Bible, donated by the Moriarty family more than a hundred years ago, has gone missing, and it doesn’t take long for the two to find themselves embroiled in scandal. Rick Riordan, author of the Percy Jackson series, says, “This tale will change the way you see Sherlock Holmes and leave you dying to know more.” In Pearson’s 4th installment of the Risk Agent international thriller series, White Bone (G.P. Putnam’s Sons), when Grace Chu vanishes in her attempt to investigate a switched vaccine in Kenya, John Knox encounters savage elephant poachers and their terrorist sponsors in his efforts to follow her trail.
