Books with title Wilfred to the Rescue

Wilfred is a young magical apprentice determined to become the best and most wise wizard that ever was. Unfortunately, he's not very good. He's got the raw talent, but he doesn't concentrate! In fact, he's become (rather unkindly) known as "Wilfred the UNwise." And when one of Wilf's spells goes badly wrong, he's suddenly catapulted into the future—and more specifically, into Bel's hometown. Bel is an aspiring magician, too—she wants to be an amazing street magician like her heroes on TV. She's even got a stage-name, and unlike Wilf, she practices all the time—maybe just a little too much. Delighted by her skills, Wilf begs to learn from Bel. She's not so sure, but agrees that they'll have to work together to try to work out how to get Wilf back to his own time. Can these two young magicians work together, or will Wilf be stuck here forever?

All her life Wren has hoped for an adventure. Now she has one—with a kidnapped princess, a handsome prince, and a magician. What does it matter if the princess is only Tess, her best friend from the orphanage; if the prince is a youngest son with no chance of becoming king; and the magician is an apprentice? Wren leads the other three over mountains and past killing spells, fighting battles along the way. But then she finds herself up against some shape-changing magic that may end her life as a human forever!
