Sacrifice by Brigid Kemmerer

Sequel to 'Secret'. Michael Merrick doesn't know how much more of things he can take. Between social services threatening to take his brothers from him, and his firefighter girlfriend's life constantly being in danger, it's hard to know where to look - and with the Guides back with a vengeance and determined to put an end to the Merrick's once and for all, he really can't afford having his thoughts all over the place. It's do or die, and not everybody is going to make it out alive.
