One of the best ways to get your books noticed is to have them on a Goodreads list (of which there are a few).
The rules, I understand, are as follows:
♦ You cannot add or vote for your own book (makes sense). Someone else has to add it for you. ♦ You must list the book you’re voting for on one of your shelves (“Read” or “Want to Read”). ♦ You can vote for multiple books, as well as prioritize them.
I’ve come across many writers requesting votes for their masterworks so that they may move higher in ranking. I get that and am more than happy to help by offering a vote or two or twenty.
Confession: me, myself and I have never done that (we’re challenged when it comes to self-promotion, but have always really wanted to give it a go). 
A dear blogger-writer friend, Jina S Bazzar added Can You Hula Like Hilo Hattie—the 2nd in the Triple Threat Investigation Agency series—on the Detective List. How cool and sweet is that? Thank you, Jina!
Journeys, a Facebook writing community, has “Shameless Saturday Promotion” . . . I’m borrowing the idea and shamelessly promoting myself on this fine October Saturday. Won’t you please vote for Hula by going to Goodreads? I’m # 493.

She’s also the author of Heir of Ashes and Heir of Doom, which feature the feisty Roxanne Fosch, a young fee hybrid who escaped a government research facility after spending nine years as a captive. I won’t reveal more. You’ll have to read the exciting books to see what transpires!
