The Wilds (The Wilds #4)

Waking in the belly of the beast - Medical Central - Daisy finds herself reunited briefly with Heather. Their time together is cut short when Heather is taken away to undergo 'treatment.' Unable to rescue her partner on her own, Daisy is able to flee Medical with the help of a mole, vowing to return with every ally she has at her back. The only thing standing in her way: the people she has sacrificed everything for, the people of the Compound.
