This omnibus was never released here in the states as far as I can tell. I finally managed to nab a copy thanks to AbeBooks. I've read the 1st two books and am looking forward to reading the 3rd and last of the series. I blame these books for my love of terminated crystals. At least a little. Fun fact: amethysts fade if left in the sunlight. Shown is Celestite, Amethyst, Green Florite (I think.) and various kinds of Quartz.
