The Renegades Book 6: Temporal Trouble - The Renegades, #6

Being a thirteen-year-old superhero wizard is not easy.  Just ask Mike.  He's picked on by bullies at school, has to help take care of his younger siblings, gets treated like a kid by the rest of his Renegades teammates, and has an evil witch voice in his head. But things are going to get worse before they get any better when Mike finds himself trapped in a time loop.  Stuck repeating the same day over and over again, with no end in sight, and no way to get help.  Mike will have to master spells he's never tried before if he wants any hope of escaping.  Because this time loop was created by someone...and that supervillain has set their sights on the source of Mike's magic: the legendary Book of Darkness.
