Land's End Trilogy

When Rowena falls through her classroom wall and lands in an alternate world, she doesn’t count on being kidnapped - not once, but twice, dammit - and the stakes get higher as the men get hotter. Unwanted husbands keep piling up, but that doesn’t stop her from falling for the wrong brother. Not only that, she has 18-year-old Kendra to look out for and a war to prevent. Good thing she has the ability to go back through the wall.

When Rowena is abducted back to medieval Land’s End, all is in turmoil. Gareth is trapped in the middle-world. Cedric is losing his soul to the black arts. What’s a modern girl to do? Learn how to control her powers of magic, of course. Things go wrong when she accidently conjures up a Roman Legion in mid-battle. Now she has to prevent Roman and Land’s End warriors from killing each other. 

As Cedric fights battles down south, Rowena unwittingly rides into an enemy war camp and is taken prisoner by her old friend Lars, who is not what he seems. Yet Rowena is not helpless. After all, she is a hereditary half-witch with a whole lot of magic in her. Too bad she doesn’t know how to use it. Escaping from the camp, she continues to botch up spell after spell. Soon Kendra joins her on the trek back to Huel, along with the latest magical mistake, a flame-burping dragon called Cinders.
