This book is the sequel to K.A. Tucker's novel The Simple Wild. I read The Simple Wild earlier this year (which I rated 5/5 stars) and was really excited to see the continuation of Jonah and Calla's story. I would highly recommend reading the first book in the series before tackling this one so that you can get to know all of the characters and their backgrounds. Wild at Heart is a realistic look as to what life looks like once couples have been together for a longer period of time and move in together. There are arguments, but there is also a deeper sense of love between the two. After some consideration, I do think I enjoyed the first book more, but this story is still fantastic. I especially loved Jonah and Calla's grumpy neighbor, Roy. I tend to be drawn to the odd characters in books and tv shows (think Dwight Shrute from The Office or Charles Boyle from Brooklyn99) and he definitely fits that archetype. I have heard some rumors that another book is on its way in the Wild series. If that is true, I will definitely be reading that one as well.
