Overall, I liked it. I really enjoyed 2 of the three. 
 A Tangled Web by Mercedes Lackey - this one was OK. Mistaken identities, Greek gods, Norse heros, centered around Persephone's abduction by Hades (an abduction she whole-heartedly agrees with). 
 Cast in Moonlight by Michelle Sagara - I love the Cast series, and this fits in well. It's Kaylin's first day witht he Hawks, and how she comes to join them. No more answers, but you can see how far Kaylin has come/evolved. 
 Retribution by Cameron Haley - my favorite story out of the three, Domino (from Mob Rules) needs to escape a death curse and the Angel of Death. Good story, characters & action. Enjoyed seeing more of Mr Clean, too. Really hoping that we'll see Samael in a future book.
