The Archive (Maer Cycle book 2) by Dan Fitzgerald

SFFOasis

In Hollow Road three companions discovered the monsters of legend were all too real… Rumors among the Maer tell of an underground library called the Archive, which houses a wealth of knowledge and terrible magics that could be used to start the biggest war seen since the Great Betrayal. A mixed group of humans and Maer set off on an historic quest to find the Archive and protect it from those who would use it to destroy everything they hold dear. As the cold of winter bears down upon them, they trek through forbidding mountains beset by dangers they could have never imagined. They follow a set of ancient clues deep into the Silver Hills, forging surprising alliances and making new enemies. The humans and Maer are linked by more than their quest to find the Archive and stop an insidious war. A mystical surrogacy may bridge the gap between two peoples, and many hearts entwine as their adventure hurtles toward its bloody conclusion.

Bad End by A M Blaushild

Archangel Michael's death at the hands of Iofiel may have prevented him from forcing the apocalypse, but it's hardly brought peace. The new Archangel Michael is relentless in his quest for revenge, believing Iofiel is still out there- and shirking his duties to prove it. Afraid of his connection to the traitor, Maalik has fled to Hell, also looking for Iofiel- but what he finds instead is an oddly amicable Morningstar with shocking plans that Maalik may be unable to stop. Archie and Salem, abducted and now working as assistants for the devil, struggle to define their place in what is about to unfold. And on Earth, Santiago and Damien have found refuge in a small American town, comfortably leading a coven of witches. But when magic begins to crop up among ordinary humans, their disguises can only last so long. And what ever happened to Iofiel, The Saintkiller, the Second Traitor? The apocalypse may have been averted, but something is clearly going wrong.
