What a great book! i loved the first one and loved the second. I really enjoyed reading Of Poseidon, mainly because i love Anna bank's writing style. Its so witty and easy to get into and Emma's POV makes it even more fun to read. She's actually one of my favourite protagonists because she is so normal without being boring or pathetic and her sense of humour makes me laugh. 
 Galen is totally sweet and cute and adorable and i love those two together. Nothing major happens to their relationship but after the cliffhanger i am really excited to see how it develops in the next one. 
 I m not usually into mermaid stories but i found the plot actually quite interesting. It revolves around Nalia who is the long lost princess with the gift of Poseidon and how she has to try to get her place back. There werent any special twists or anything but its still interesting enough to keep you hooked. 
 I wasn't a big fan of Rayna but i really like her now as well. I love how she is a bit crazy and has temper issues and was quite fun to read about. 
 This series has grown on me and i m looking forward to the sequel. Not quite sure which direction its going to go after this but i m excited for it.
