Getting Even by Kayla Perrin

Claudia has been planning her wedding, destined to be the event in Atlanta's black society. But when she is stood up she's stunned and humiliated. Annelise is frustrated. How long can a woman go without getting some from her husband? The man she supported through law school, who she signed a prenup for. But it seems the man who used to want it all the time is still getting it . . . from another woman. Thank goodness their single friend Lishelle has a couch to spare. But when The Guy Who Got Awayreappears in her life, she starts envisioning marriage. Ignoring her friends' advice, she agrees to guarantee his bank loans for a new business.  Once he gets his hands on her money, he disappears. As the scorned friends bitch over a bottle of wine, an idea takes shape -- letting these weasels sink quietly out of their lives is too good for them.

These women want revenge.

The Thirteenth: Vampire Huntress Legend by L. A. Banks Book 12

The entire Neteru Guardian team is on the run, having now been labeled as America's most-wanted terrorists following the gruesome demon battle that felled the Washington Monument and crashed the front doors of the White House. The Anti-Christ is positioned for emergence, the powers of darkness have released the pale horse of the apocalypse, and half the Neteru team is pregnant. Plagues from hell that ravage the country are being cited as stemming from bio-terrorism. The nation is under martial law. The Neterus and their team are underground. If things weren't bad enough the Dark Realm breaks the sixth Biblical seal, which plunges the world into perpetual darkness…and irrevocably into the Armageddon.
