House of Desire (Book 14 of Silver Wood Coven)

As the race winds down, the heat turns up. Although the rogue Wiccans have managed to take the first two Fae crystals, two others remains at large. But as Summer's team lands in 1871 Chicago, they begin with a crisis. Summer lies unconscious from a head wound as Troy and Michael try to get help. Meanwhile the Templars suspect each other of betrayal, and the Fae member of the team inexplicably disappears. As the date for the Great Fire nears, the fractured team relies on outside help to complete their mission. But the rogue Wiccans have some special help of their own.
