Here Comes the Sun (Eclipse #2)

When Mason discovered his quiet professor boyfriend, Lan, was a werewolf he was thrust into a world of trouble. Lan is becoming an important man in the new and peaceful were-government, but the wolf packs are not going to let go of power easily.

Mason is not trusted by any of the werefolk, adrift in his life, and his diffident lover is fast becoming an uncontrollable wolf--as enemies close in on them all from every side. A natural alpha male all his life, Mason realizes that every enemy and even his own lover could easily overpower him. But none of them are ready to do what it takes to save the werewolves' human victims.

To keep his lover and his life Mason must learn to control forces greater than himself, and take a stand against his enemies even if he cannot hope to defeat them.
