Stodgy British archivist Henry Percival-Smythe slaves away in the dusty basement of Ealing College in 1934, the only bright spot in his life his obsession with a strange Australian mammal, the thylacine. It has been hunted to the edge of extinction, and Henry would love nothing more than to help the rare creature survive.Then a human whirlwind spins through his door. Jack "Dingo" Chambers is also on the hunt for the so-called "Tasmanian Tiger," although his reasons are far more altruistic. Banding together, Dingo and the newly nicknamed Dash travel halfway around the globe in their quest to save the thylacine from becoming a footnote in the pages of biological history.While they search high and low, traverse the wilds, and fight the deadliest of all creatures—man—Dash and Dingo will face danger and discover another fierce passion within themselves: a desire for each other.
