Dragons in a bag

In Brooklyn, nine-year-old Jax joins Ma, a curmudgeonly witch who lives in his building, on a quest to deliver three baby dragons to a magical world, and along the way discovers his true calling.--

Now that he is Ma's apprentice Jax is finding himself mixed up with all sorts of magical doings, like taking care of a phoenix egg which is going to hatch soon, trying to bring back the creatures Sis stole, finding his grandfather, and convincing Sis, the guardian, to reunite the two realms--and hopefully living to see Brooklyn again.

Amidst the search for a peaceful resolution, Jax and his friends find themselves facing an imminent war as the witches gear up for battle against the formidable Scourge, threatening to drain all magic from both realms.
