Hell of an Angel by Christi Barth

Raised in Hell. Living in Buffalo. And on the verge of accidentally destroying both realms…

Dark angel and actuary Evangeline Thayer hates taking unnecessary risks, but she knows becoming human will be worth it. All the creatures in Hell have bullied her about her negligible ‘power’ her whole life. And don’t get her started on why she has wings if she can’t even fly?!? She just needs a teensy bit of help with removing her power…which is where a very hot, very flirty, and absolutely infuriating Nephilim comes in.
Half-angel Gideon Durand has been fighting demons a long time, but he’s never heard of a dark angel. Least of all one this gorgeous, stubborn, and with the power to completely nullify evil. Maybe in Hell, that’s a weakness-but with an unknown evil on the loose and murdering Nephilim?-that’s a damned useful skill. So Gideon strikes a deal with Evangeline: he’ll scratch her wings…if she’ll scratch his.
Now good and evil are-temporarily-working together. And might even be having steamy fun…if it wasn’t for a rather inconvenient threat trying to unleash the apocalypse, once and for all.
