Coble (The House at Saltwater Point) wows with this suspense-filled inspirational that follows a woman trying to piece together her past. Thirty-year-old marine biologist Harper Taylor, who grew up in foster care, is desperate to find her biological family. After she takes a DNA test, the testing company sends her contact information for her half-sister, Annabelle Rice. Harper rushes to meet her, and the sisters quickly discover they have more in common than the same unknown father. Annabelle and Harper both lost their mothers at a young age, and both have been victims of recent attacks: Harper's houseboat was broken into and she was attacked while diving. On the same day, Annabelle was stabbed with a needle and woke up trapped in a trunk that she was barely able to escape. Harper and Ridge, the son of her boss and an older brother figure to Harper, begin to search for answers and connections between the two attacks--which might also be connected to the deaths of Harper's and Annabelle's mothers. As they work together, Harper and Ridge develop feelings for each other. But Harper is worried a complicated history with Ridge's father might ruin their chance at happiness. With startling twists and endearing characters, Coble's engrossing story explores the tragedy, betrayal, and redemption of faithful people all searching to reclaim their sense of identity. Fans of Susan May Warren will enjoy this. (Sept.)
