Firstly I loved this story! The whole twist on the tale of Hades and Persephone is always interesting to read and this is no exception. On the minus side this was the third book in the series and as so often happens the third book wasn't as good as the first and it makes me question if three books are even needed.
So Kate had been kidnapped by Calliope and Cronus in the huge cliff hanger that was the second book and is about to pop with child. It seems like there is no story if someone you love isn't torn away from you, leaving you behind to bring them back. Kate and Henry went through their fair share of apart, together, and apart again so its only natural that this book follows that vein and continues the tradition with their family. This is a highly addictive story technique; even though I figure they will end up happily together in the end I just have to keep reading to be certain, because sometimes they throw you for a twist.
Overall I thought this was an ok book and a very good series, I recommend this series to anyone who likes to read books that retell or play with mythology. A few books I've read that remind me of this are [b:Abandon|9397967|Abandon (Abandon Trilogy, #1)|Meg Cabot|http://d202m5krfqbpi5.cloudfront.net/books/1324767084s/9397967.jpg|11351526], [b:Starcrossed|9462795|Starcrossed (Starcrossed, #1)|Josephine Angelini|http://d202m5krfqbpi5.cloudfront.net/books/1358266716s/9462795.jpg|10862992], [b:The China Garden|82648|The China Garden|Liz Berry|http://d202m5krfqbpi5.cloudfront.net/books/1171024515s/82648.jpg|1182296], and [b:Everneath|9413044|Everneath (Everneath, #1)|Brodi Ashton|http://d202m5krfqbpi5.cloudfront.net/books/1340210035s/9413044.jpg|14297146].
