Well, I have you beat in every way on the regret front.  Eight years ago, I made a deal with the Extinctionists.  For one rare, almost-extinct lemur, I was given the money I needed to search for my father in the Arctic.  At the time, it seemed like the perfect solution, and I didn't really have any qualms about environmental affects if it meant I would find my father.  I haven't really given it much thought since then.

Except now, my mother has been struck down with a deadly virus, that I make life-threatening when I try to cure it with magic.  It turns out that the silky sifaka lemur that I gave to the Extinctionists those eight years ago is the only creature that can save my mom.  Funny thing, they are all now-extinct- because of my actions.  I will have killed my mother unless I can find a solution.

So, I tell one little lie, and convince Captain Holly Short to help me.  We take a little trip back eight years to retrieve the lemur and save my mom's life.  Simple, right.  Of course not, cause I'm me and hijinks, adventure, confused identity, body switches, possible love interests, betrayel, and an old nemesis in the form of Opal Koboi ensue.

However, time is running out, and with Opal in the mix, I'm not sure I'll be able to pull off the kidnapping of the extinct lemur, saving my mom, and fixing the time paradox I've created.  (Book Talk Author: Tobye Ertelt, The Colorado Blue Spruce Award nominee 2012)
