One-sentence summary

On Randy Ingermanson’s blog he is critiquing one-sentence summaries from his faithful blog readers. I’ve been waiting for this, as I’m never sure if I’m doing it right. Here’s my entry for my Nano-novel, Gift of the Ancients:

The idea is this becomes your elevator speech when talking about your novel, and it gets used as back cover copy and in various sales pitches.

Would this catch your interest? How could it be better?
