These are all fantastic stand-alones and there is something from every genre!
If you are in the mood for a paranormal stand-alone, you should read Girl Under Glass by Monica Enderle Pierce. I am putting this one right at the top because it was amazing and because I never hear this book talked about! Seriously it is SO good you guys, check out the Goodreads summary, you won’t regret it.
For a standalone western I can’t recommend Vengeance Road by Erin Bowman enough! I love the slow romance, the MCs determination and the setting. The author really drew me in until I could feel the heat, taste the dusty dry air and hear the buzzards.
If a science fiction standalone is more your taste then might I talk you into Origin by Jessica Khoury
And last but certainly not least I have a collection of fantasy stand-alone recommendations. These are all outstanding and you NEED to add them to your TBR. East by Edith Patton , The Emperor’s Soul by Brandon Sanderson and The Scorpio Races by Maggie Stiefvater
And that is it for my list of best stand-alone novels, now I want to hear your recommendations!
