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.

A prophecy is only real when allowed to occur naturally, so when a series of unexpected events happen in the summer before 5th year, a second prophecy long lost deep in the Ministry of Magic awakens, telling of rare magic and an incredible bond to be forged between the most unlikely people. This magic and bond will be the end of the Dark Lord.

It all started with an unexpected meeting at King's Cross at the end of Harry's first year. The next thing Severus Snape knows he's stuck with the Potter brat.
