That's the Trouble with Time — L. Darby Gibbs

Quinn Riley needs to be approved for his solo time jump. Have backpack, will time travel.

He's selected his grandmother's best friend, a woman who went missing after her last mission. It's a test he'd better not fail.

Sarra Marsh is occupied with avoiding the pSychSo officers and generally making life difficult for the oppressive government the renegades are trying to overthrow. She doesn't have time to babysit the first-floor neophyte that dropped into their midst and help him locate his stolen backpack.

Puff is devoted to Sarra. He's a sweet white puffball that likes to adorn her braided hair. He's also adorned with sharp retractable claws, frightening razor teeth and a unique way of taking to the air.

They make a formidable team. Quinn should never have joined it.

Can Quinn accept that Sarra would rather die than walk away from the war her father set in motion? Can Sarra keep her heart from shifting her loyalties from an ideal to the man she has grown attached to?

Quinn has to survive his solo time jump. Is it worth it if Sarra doesn't survive hers?
