Pride Publishing has been working on getting back list series into Kindle Unlimited, so if that's one of the ways you read, I have some series for you :D
Three of my series are now available on KU - and this includes individual books as well as boxed sets:
Endangered Fae (urban fantasy - 4 books, complete)
Angel writes (mostly) Science Fiction and Fantasy centered around queer heroes. Currently living part time in the hectic sprawl of northern Delaware and full time inside her head, she has one husband, one son, two cats, a love of all things beautiful and a terrible addiction to the consumption of both knowledge and chocolate.
