Dust Thou Art — Robin Buckallew

Volume 13 of the Leafy Tom Series. When Phoebe starts her own team, she is glad they will remain part of Anikka's team; most of her team is teenagers, and only partially trained. In Phoebe's world, nothing goes as promised. Her new team is thrown into a mission without the adults when the adults are missing and the only thing at home is piles of dust and medallions. A cryptic message sends the team to Oklahoma, where they join forces with a Texas team to try to bring the witches back home. They face dust witches, humans, and the Minnetka of bats. Everything depends on a team of half-trained teenagers; Phoebe hopes they are ready.
