E: The False Princess by Eilis O'NealSorry I had to use an author's name, but I'm sure E's will be hard to come by and I used up all the F's and P's. I loved this debut novel. It isn't what you expect and that's a good thing.
June in Winter of course starts with a J, not a K! Grr, typos!
I now have June updated.
J: The Jinx by D. F. LamontThat makes J and E for June.
