Prowl, the second book in USA TODAY bestselling author Colleen Coble's Sanctuary series (following Ambush), delivers exactly what her fans want: the ideal blend of suspense that keeps you on the edge of your seat with just the right amount of romance. Perfect for fans of Laura Dave, Allison Brennan, and Dani Pettrey.
When a worker at the Sanctuary is discovered dead in the tiger enclosure, authorities assume the big cat killed her. But when the autopsy shows she was killed by a lethal dose of anesthetic delivered by a tranquilizer gun, suspicion falls on Blake Lawson, co-owner of the Sanctuary. Blake has his hands full trying to clear his name as well as get the Sanctuary finances back in the black. When a soil test turns up traces of rare earth, he's even more puzzled. Is someone trying to run them out of business to get to whatever is under the ground?
Meanwhile, wildlife veterinarian Paradise Alden is determined to find the brother she only recently learned even existed. When the results of the DNA test she ran mysteriously disappear from her portal before she can read them, she realizes someone must not want her to know the truth. A break-in at her new apartment is alarming, but she tries to pass it off as someone trying to scare her away. She refuses to turn tail and run when she is desperate for answers.
For Blake, the only solid ground is his relationship with Paradise, and he longs to propose--but how can they even think about starting a life together with so many forces working against them?
Colleen Coble's Prowl combines gripping suspense with closed-door romance and includes intriguing mysteries from both the past and present, sabotage and danger, second-chance romance, found family, and themes of overcoming pain and how the past doesn't have to define you.
