First up is the Riley Bloom Series by Alyson Noel. I've already read the first book, but that was when it first came out 2 years ago, so I'm going to reread it.
The second is a new series that just came out by Kim Harrington called Sleuth or Dare. The first book came out May 1st, the second June 1st, and the third will be released on July 1st.
Partners in Crime
Framed and Dangerous
The final book on my list is one that was recommended by one of my critique partners, Archana Bharathan from Writers By The Shore.
