Alpha & Omega
Short story, beginning of the series. Featured in 'On the Prowl'

Cry Wolf
Anna never knew werewolves existed until the night she survived a violent attack…and became one herself. After three years at the bottom of the pack, she’d learned to keep her head down and never, ever trust dominant males. But Anna is that rarest kind of werewolf: an Omega. And one of the most powerful werewolves in the country will recognize her value as a pack member—and as his mate.

Hunting Ground
Anne Latham didn't know how complicated life could be until she became a werewolf. And until she was mated to Charles Cornick, the son--and enforcer--of Bran, the leader of the North American werewolves, she didn't know how dangerous it could be either...

Anna and Charles have just been enlisted to attend a summit to present Bran's controversial proposition: that the wolves should finally reveal themselves to humans. But the most feared Alpha in Europe is dead set against the plan--and it seems like someone else might be, too. When Anna is attacked by vampires using pack magic, the kind of power only werewolves should be able to draw on, Charles and Anna must combine their talents to hunt down whoever is behind it all--or risk losing everything...
