With Halloween fast approaching, Cassie and the town of Middleton are hard at work preparing for the annual Harvest Festival. This year, Cassie is transforming Grey House into a delightful haunted house, and when a handsome stranger checks in, the family suddenly find themselves on edge.

Cassie and Sam decide to take a step forward, but his pushy ex-wife stalls them at the starting gate. Grace preps for the teenage rite of passage -- her driving test.

The arrival of a man from Cassie's past may complicate her burgeoning relationship with Sam, but that isn't the only bump in the road - Sam's intrusive ex-wife Linda is still trying to keep Cassie out of the picture in a desperate attempt to repair their fractured family.

The author of a series of magic-and-romance-filled novels comes to Grey House to celebrate the release of her newest book, titled "The Enchantress Unites." But it's Cassie who ends up doing the uniting, bringing together the people of Middleton to put on the special event while also coming to a special realization about Sam.
