The Rewilding by Robert Evans

When curiosity doesn’t kill the cat… the cat might just kill you.

In the quiet of the Scottish countryside, a young boy has been killed.
Nobody is sure how… or by what.
This inexplicable death piques the interest of field biologist Steph Patel who, motivated by the chance of a money maker, pursues the boy’s story.

Discovered near the secret location of a rewilding project, where geneticists are working to bring back once-extinct predators, the boy’s death is suspicious to say the least. But when Steph probes further, things rapidly go south, and she soon finds herself fighting for her life against enemies far more dangerous than anything resurrected from the past.
