I loved the Mercy Thompson and Kate Daniels books. Can someone suggest similar books? With powerful women, alpha males and good world building.

Authors to consider from my friend Kerry -

Nalini Singh.
Karen Chance.
Faith Hunter.
Grace Draven.
Jean Johnson.
Katie MacAlister.
Lilith Saintcrow.

I'll second Nalini Singh. Especially her Guild Hunter series. Elena and Raphael kick butt!

I have read Nalini Singh, Karen Chance & Katie MacAlister. Will definitely check out the others.

Kim Harrison- Rachel Morgan (aka The Hollows)
New books being added by author to the " ended " series. Million Dollar Demon due in June

the Demigod series by KF Breene. She's written other stuff as well but not as good imo

Definitely Nalini Singh (Psy-Changling is probably the closest with shifter/Psy/humans but Guild Hunter is awesome too with angels/vampires/human).

Anne Bishop's The Others series (shifters/human/other, but no sex).
Seanan McGuire's October Daye series (Fae+, sex-off-the-page or just-a-peek after the SLOW burn)
Alex Craft series by Kalayna Price (Fae/witches/ghosts/human, love…thing.)
Dorina Basarab series by Karen Chance (Vampires/Fae+)
Charley Davidson series by Darynda Jones (no spoilers, SCORCHING hot sex)

Have you read the Alpha & Omega series by Patricia Briggs (same Mercy world, with Anna & Charles)?

I'm also searching for similar authors.

Other good UF books and authors imo:
The Sixth World Series by Rebecca Roanhorse
Dirk & Steele by Marjorie M. Liu

From the entire list given, the only up there quality wise, with Illona Andrews and Patricia Briggs, is Nalini Singh.
Tried all the other ones and they range from bad writing to false advertising (NOT a romance and/or character baiting).

I tried Faith Hunter's Jane Yellowrock recently but I dnf. It ISN'T a romance and

SPOILER!






No HEA. There is no relationship for a HEA to happen.





END OF SPOILER,

I made a list of other authors I that were a miss for me and why (hope it helps a little).

Gena Showalter (lazy writing and false advertising)
Sherrilyn Kenyon (lazy writing, rape for "character building", character baiting/queer baiting)
Keri Arthur (no character development whatsoever, flat characters ALL of them, got into Nora Roberts' level of lazy STILL in the FIRST book)
Grace Draven (good world building and character building, after they have sex, 'though, that's the only thing they do forever and EVER)
Maria V. Snyder (the romance is like an imaginary friend, it's there... barely... if you squint)
Lilith Saintcrow (you get more plot and character development from pornhub. and pornhub is free.)
J.R. Ward (good world building and characters until they have sex, character baiting, J. K. Rowling Syndrome "aka" ruining her own books by writing unnecessary new ones, reversing HEAs "they were happy... BUT NOT ANYMORE! )
Carolyn Crane (bad character building and development, unlikable narrator, character baiting)
Jennifer Estep (unlikable narrator, unlikable characters in general, bad at romance writing)

Most of the ones I wanted to recommend are already listed.

Try also:

- Thea Harrison
- Jeaniene Frost
- Karen Marie Moning

I can't recommend Nalini Singh enough if you haven't read her. Her characterization and relationship building are top notch, and you get feels all over the place.

Also seconding the vote for Seanan McGuire's October Daye series. Brilliant, strange, and terrifying world building and characters.

Im currently enjoying the Girl in the Box series by Robert J Crane - it initially felt a little YA but it isn't catergorised as such and after the first book doesn't feel like it either. I've read most of the others suggested here and have enjoyed them all.
