I've read the Zenity triology by Leanne Davis, and I've read the River's End series. When I got the chance to read a copy of one of Leanne Davis's Sister's books, I jumped at the opportunity. What an amazing book filled with well-developed and deep characters who nearly leap off the page with their intelligence, bravery, and deep connections to one another. This book centers on Tony Lindstrom, the former best friend of Will Hendricks, and wounded Army vet. When Gretchen Hendricks, Will's ex-wife and former childhood crush of Tony's runs into him at the grocery store, she's flabbergasted at the change in Tony's attitude and personality. Family members ask her to step in and help; she's a licensed therapist, but she has not idea of the depth of Tony's pain and rage. Gretchen and Tony have a long, slow burn in this book before anything happens between them, but the heat they create and the chemistry....Wowza! The complications and outside stressors that combine to add to the story are heartbreaking and real - a young child is losing the only mother she has ever known, and she will become Gretchen's responsibility. The story is extremely detailed and fleshed out, and the supporting characters (most from previous books, from what I can surmise), truly help to make this a saga without end. Each character draws you into their personal lives and worlds, and I cannot wait to get better acquainted with the rest of these lovely people
