Crossover in Crossroads (Discontinued)

Alice and the other slayers go on a vacation to Crossroads. There, they meet four people, of whom they are very suspicious. Strange things always happen when they are around. Goblins trying to eat them along with zombies? Witches casting spells? People disappearing out of thin air who can take knives to the heart? The always have no clue what is happening, but they want to find out.
But answers come with prices. Are they willing to pay?

All credits to Gena Showalter, I own none of the characters.
Two books involved, the WRC and the Intertwined series. Don't complain if you end up not liking the other characters.
