Worldweavers Series

Great things have been expected of Thea, the seventh child of two seventh children. Now, with Cheveyo, a mage of the Anasazi, Thea has begun to weave herself a new magical identity, infused with elements of the original worlds. But back home, Thea keeps her abilities hidden and attends the Wandless Academy, the one school on Earth for those who have no apparent magical talent. It is there that Thea realizes that her enemies are hungrier and more dangerous than she knew.

What do you get when ordinary email spam becomes infused with magic? Spellspam - and it's not supposed to exist. As far as Thea and her friends know, computers are meant to be inert vehicles for storing magic spells, not magical processors themselves. 

Thea returns to the Wandless Academy only to discover her friends are as out of sorts as she is. It’s only when she discovers she is an elemental mage - a mage so rare that only four other wizards in history had similar talents - that the pieces start falling in place.
