Mercyverse is author Patricia Briggs's term for the universe in which the Mercy Thompson (MT) and Alpha and Omega (AO) series take place. The universe is very similar to our own, with the same geography and general history; the major difference is the existence of fae, werewolves, and other preternatural creatures.

The timeline of the two sister series are strongly intertwined, with events in one series impacting events in the other. Here is a suggested reading order following the chronological timeline.
