Kat Among the Pigeons

Katlyn is a member of a fae clan whose job is to stand the line between human and magical lands, a secret she has trouble hiding from her new human boyfriend even before she unexpectedly finds the fate of the world in her hands.

She isn't magically strong, and unlike other fae who understand all animals, she only caught birds and cats -- not a good combination. However, when she isn't able to reach other fae for help, Kat and her boyfriend frantically fight the enemy with the aid of a lazy tom cat, an African gray parrot who only speaks in verse, and a wise-cracking cockatiel with a bad attitude.

She's trying very hard not to think the world is doomed.
