An absolutely delicious imagining of the Hades and Persephone myth.  Immersive world building, fully realized characters, trademark Katee Robert heat.  Hades is one of my most favorite heroes I've read in a while, Persephone is strong and independent without veering into "nOt LiKe OtHeR gIrLs" territory, and they adopt three puppies.  Literally what more do you need?  Just the second book in the series immediately, really.
