I read cozy and historical mysteries, a bit of Paranormal/UF, and to mix it up, I read science and gardening books on occasion.

Mine is actually going to be two lists, cozies and non-cozies; otherwise, guess which one would dominate?
Cozies:
1. Lillian Jackson-Braun: All save the last two, so 27 in total.
2. Carolyn Hart: All but the most recent, 26
3. Carola Dunn: All the Daisy Dalrymple books, 24
4. Claudia Bishop: All her Hemlock Falls and Angel's Advocate series: 23
5. Jill Churchill: All the Jane Jeffries and Grace and Favour: 22
6. Kerry Greenwood: All the Phryne Fisher, 21
7. Nancy Atherton: All Aunt Dimity, 20
8. Carolyn Haines: All the Sarah Booth Delany books + shorts: 19
9. Donna Andrews: All the Meg Langslow books, 18
10. Juliet Blackwell: Everything she's written, 17
Non-cozies:
1. Janet Evanovich: An embarrassing amount of it, too high to count
2. Arthur Conan Doyle: All the Sherlock Holmes stories and books, 60
3. Judy Blume, 15
4. Chloe Neill, 14
5. Charlaine Harris, 14 + shorts (sookie steakhouse)
