Once a Princess, by Sherwood Smith– the first book of the Sasharia En Garde! duology–is currently a Kindle free e-book.
Sasha’s mother, Sun, was once swept away from a Ren Faire to another world by a prince—literally—but there was no happy ending. Sun’s prince disappeared, and a wicked king took the Khanerenth throne. In the years since, Sasha and Sun have been back on Earth and on the run. Mom and daughter don’t quite see eye to eye on the situation—Sasha wants to stand and fight. Sun insists her prince will return for them one day; it’s safer to stay hidden.
Then Sasha is tricked into crossing the portal to Khanerenth. She’s more than ready to join the resistance, kick some bad-guy butt, and fix the broken kingdom. But…is the stylish pirate Zathdar the bad guy? Or artistic, dreamy Prince Jehan?
Back on Earth, Sun is furious Sasha has been kidnapped. Sun might once have been a rotten princess, but nobody messes with Mom!
Warning: This title contains a kick-butt mother-daughter team, a wicked king, a witty pirate with an unfortunate taste for neon colors, inept resistance fighters, a dreamy prince who gallops earnestly hither and yon, and a kick-butt princess in waiting.
