Got New Book And Have Question About Very Old One??

Well, got DKs latest, "Your Heart Belongs To Me," for Christmas, and
began part 2, into that ,a chapter or two, already, this evening. When
I discussed DK in another grp. I particpate in, one poster, who said
that he wasn't that impressed with DK>>>GRRRRRRRRRRRRRRRRRRRRR>>MY
FAVORITE AUTHOR , mentioned having read a DK book named, "Warlock."
Well I thought that I had read EVERY SINGLE ONE, up to including
reading his newest. But I had never heard of Warlock. So I Googled it.
Yup, there it was 1972, all long time ago, in a galaxy far far away. I
found several on amazon, but all paperback, and not very reasonable at
that for a paperback. Maybe in the library???

Have any of you here, read that one?? Is it any good, worth pursuing??

TIA
