A Wizard Abroad is the fourth book in the So You Want To Be A Wizard series by Diane Duane. Nita's parents are worried about her relationship with Kit so they send her to visit her Aunt Annie in Ireland for a few weeks. Nita is careful to let them know that she will still be a wizard on call even while on vacation. Ireland turns out to be a mess of magic. Spells done there linger for centuries so that the common magic Nita is used to doing can have serious consequences.

Nita meets many wizards and gets an expanded understanding of how the management structure works internationally. Nita becomes a connector of sorts between people of different ranks, the Powers, and sifferent types of non-human beings. During the peace and fighting, Nita's interest is distracted from Kit but not in the way her parents had hoped.

Nita’s parents decide to send her off to her aunt in Ireland because they think she and Kit are getting too close. Unbeknownst to Nita, her aunt Annie is also and wizard and Nita finds herself in the middle of what is potentially her most dangerous mission to date! ( )
