Harry and Snape are back at Headquarters, and the stakes to find the spy are higher than ever. As members of the Order of the Phoenix begin to turn on one another, more is happening in the background than any of them are ready to expect. 

When Harry blows up Aunt Marge, Dumbledore decides he can't be left to his own devices in Diagon Alley for the whole of August and sends him to stay with the only person available - one highly displeased Severus Snape. Harry, for his part, doesn't think this summer could get any worse. After all, what could be more unpleasant than living with Professor Snape?

Finding out that Draco Malfoy is also staying at Spinner’s End, of course.

None of them know how they'll survive a month in each others' company, but they might just come out the other side with something they all need the most: a family.
