The Gay Teen’s Guide to Defeating a Siren: Book 3: Sanctuary

Three months have passed since Sanctuary was shut down, and Blaize is still struggling to accept the Siren’s identity. It’s emotional hell, but that doesn’t stop the government from using him and his special ability. They’ve hidden Blaize in a secret military base, with the sole purpose of capturing the single largest threat in the world. Someone he once called a friend.
Before they can stop her, the Siren strikes, using her power to steal a secret weapon. Worse, she sets her master plan in motion, turning thousands into slaves in a twisted experiment to purify the world.
Now, Blaize must retaliate, but the line between friend and enemy becomes blurred when the Siren returns home. There, Blaize will have to confront his past and sacrifice someone he loves, or everything he’s fought for will be lost.
Lucky for Blaize, he wields the ultimate weapon–being gay. And he’s better at it than ever.
