QUEEN OF SONG AND SOULS
This fourth chapter in what has turned into a quintet works primarily to set up for the final book. It's not a series that can be picked up in the middle, because Wilson jumps directly into the fallout from the previous books, but it's complex and riveting.
Cast out after using dark magic to save the tairen species, Raine and Ellysetta won't back down from their fight to stop the advance of the evil Eld Mages. One problem is that Ellysetta carries four mage marks and is in danger of being controlled by the High Mage of Eld. Only completing their mating bond can save her, but so far they haven't been able to. Upon learning of an advance by the Eld army, Raine tries to build alliances, but Eld infiltration makes that difficult. These are dark times, indeed. (LEISURE, Nov., 496 pp., $7.99)
