Thank you! Yeah, it's definitely Of Its Time. And I think the worst thing is that you can't tell from a glance that it's time travel, and not fantasy historical. (which is what I was going for with a wave at an hourglass shape and the clock above--the previous book in the series had the time travel happen via a glowing pearl-like orb, which I put on the cover, and had this one be a portal, to continue the orb-like theme.)
