simply amazing
Format: Kindle
The intimacy, the sapphic love, the connections across all of Anna Stones books is the perfect cocktail for an amazing read. Full of ups and downs and highlighting the raw beautiful power of women and bdsm in a positive manner that’s holds nothing but respect for all consenting parties. Again amazing.

Another Wolf in the Syndicate??
Format: Kindle
Another thrilling read of Persephone Black and the amazing mafia romance. This is Ariadne’s story. She is now a recruit at the Syndicate even though she is beyond advanced but she has to earn her status. It’s kind of hard to do when she skips therapy, ices everyone out and is always on guard. Sunny is kind and warm and personable. Total opposites. They are paired to spar as a team and find that they move well together. They also seem to see more in each other than meets the eye. Well written and engaging read! Loved the pace and the spice flowed well with the story. Highly recommend!!

Yet another good read.
Format: Kindle
I love these mafia books. I’ve read all the series, and they’re all interesting and wonderful books. There’s violence, of course, and suspense, camaraderie, and steamy sex scenes. I hope there will be a sequel to Lone Wolf. If not, hopefully there will be more from this author. She’s written some great stories.

A Styx Syndicate Eccentric Story!
Format: Kindle
Ariadne/Sarah gets her chance. Not only to prove herself worthy of being on the Styx’s team but also to show she is capable of doing the things how the Styx Syndicate does it not what was inbred in her mind by Grandmother. That part has been hard and skipping therapy is not going to help. But when Lyssa & Scarlett bring back from the recent mission, a woman who was also under Grandmother’s control, things start to take a very different turn. Add to the mix, Sunny Santiago. There is something about this woman that seems to get to her but she is not sure why and knows she must control her emotions. But Sunny has other ideas. She is a new recruit vying for the same role on the team. Sunny also can’t get Ariadne off her mind. Her control is impressive, her demeanor is stoic but she is hot and in wicked shape and Sunny just wants to break that tough exterior. Sunny has a mission of her own. But when they are teamed together for a mission, definitely a test by Ariadne standards, things happen. For one stupid moment, Ariadne lets her guard down and she finds herself in an uncomfortable position and doesn’t know why. Again we have the team back and probably getting ready for their toughest mission. Love this group!
