Help needed on book cover, a picture of a crack in the ice, flipped upside-down

[Thogdin]

Absolutely didn't note them down at the time, but in the last two years or so there have been at least two horror books that have had upside-down cracks in ice as covers. I mean, a picture of a crack in the ice, flipped upside-down. Anyone out there able to help a forgetful old man out? Your help, of course, greatly appreciated if so.
