Full review here. 
 I don't know why it took me so long to read the Medus Girls trilogy because I read all of Tera's other books last year and loved them. I'm so glad I finally got into these because they might be her best. I shotgunned this trilogy like I've done to shows on Netflix, and it was awesome. I'm still having a kind of Greek mythology hangover now from reading all of them so fast. 
 Sweet Legacy picks up only moments after the end of Sweet Shadows. The girls and a couple of the boys head into the realm of the monsters to look for the Gorgons. Action flies fast in the first few pages, but there are some sweet moments too, particularly with Greer and....someone. ;) I think Tera did a fantastic job with the pacing of this trilogy. The action-packed fights are interspersed with plenty of those soft and quiet moments, whether those moments are sisterly bonding, the girls with their respective paramours, or Grace doing something scholarly. The information and mythology also flows at a good rate with no info-dumping. Nothing feels forced. Even with all the pairing up and the speed with which the girls learned to trust and love one another, I thought everything felt pretty natural. 
 It's obvious that Tera does a ton of research when she writes, and it really pays off. She may take some liberties with the time-honored myths we all know and love, but as I said above, it feels authentic. She flawlessly weaves mythological history with modern twists that only sixteen-year old triplets could inspire and plops everything in front of the rich backdrops of San Fransisco, the realm of the monsters, and even Mt Olympus itself. 
 Basically, Sweet Legacy is a great conclusion to a really fun and well-written trilogy. The characters are sypathetic and relatable. The setting is detailed and fresh. The romance is light and sweet. The action is intense. The mythology is believable. You should go read it.
