Division of the Elements

Just as things begin to settle down for the Dells sisters, they are thrown into yet another vortex of adventure and danger. The girls must suffer through betrayals and evil plots - and come out the other side in prime fighting condition. They meet new friends and foes, and must decipher the line between good and evil, or else lay trust in the wrong person's hands.
The Night Squad is back in full force, led by the cruel Jack and Stacie Night. They are after the Dells sisters' Elemental powers.
The girls must pick between two evils. If they choose wrong, their lives will be in even greater danger. And they may not survive.
Meanwhile, they each also battle internal demons, which may just be more dangerous than fighting evil organizations.
