Apparently The Secret of the Spiritkeeper is slated for an August release. The date currently on Wizards’ website is from the original plan, before they decided to release the first and second books in the series at once. This is good news, as it should give Wizards more time to rev up the marketing machine. They have plans for a full website and book club to support the line, which should help crank up the interest too.
