Escape From B-Movie Hell by M T McGuire

SPSFC

If you asked Andi Turbot whether she had anything in common with Flash Gordon she'd say no, emphatically. Saving the world is for dynamic, go-ahead, leaders of men and while it would be nice to see a woman getting involved for a change, she believes she could be the least well-equipped being in her galaxy for the job. Then her best friend, Eric, reveals that he is an extraterrestrial. He's not just any ET either. He's Gamalian: seven-foot, lobster-shaped and covered in Marmite-scented goo. Just when Andi's getting used to that he tells her about the Apocalypse and really ruins her day. The human race will perish unless Eric's Gamalian superiors step in. Abducted and trapped on an alien ship, Andi must convince the Gamalians her world is worth saving. Or escape from their clutches and save it herself.

Few Are Chosen (K'Barthan #1) by M.T. McGuire

When you're running from a murderous government and work for an equally murderous gangster, accidentally torching his apartment is a bad move. The Pan of Hamgee just wants a quiet life but destiny has other plans.
