After Dr. Brand Delaney's capture and rescue, the White Falls pack is desperate to know more about the secretive group Gecko Labs. But Gecko has beefed up security since their last break in, and getting in with brute force is impossible. After discovering the lab experimenting on shifters, Alpha Alice Williams needs someone she can trust to go undercover at Gecko Labs. Eric Lundgren is an alpha, a loner and a geneticist, which makes him the perfect wolf for the job, though he feels completely out of his depth, even more so when he finds his mate among the prisoners. Omega Victor Cowen, "the human calendar," spends his days counting seconds, minutes, and hours, trying to make sense of the passage of time in captivity. The lights are on all the time; the meals come at irregular hours. The only way the prisoners know what day it is by Victor's calculations. When Victor finds his mate, he feels beyond betrayed that the man is working with his captors. But Eric quickly finds a way to tell Victor he is there to help, and for the first time, Victor feels a sense of hope. Before Victor, spying on Gecko Labs was an academic challenge, but now his mission is all too personal. The longer Eric stays, the harder it is to hide who he is and his connection to the captive omega, but if he is to save him, he must.
