Adult Crossover Series Titles

The top line of each entry has series information; the second line contains the title, ISBN, and DOP for the first book of the series. And though a few series began years ago, most of them are still ongoing or have just recently wrapped up. You’ll find fantasy, horror, mystery, and realistic and historical fiction. There’s even a series narrated by a dog.

If you have any other recommendations, let me know in the comments section!
