   Summary

   When a young Pure Vanilla Cookie discovers fragments of Shadow Milk Cookies shattered Souljam, he wasn’t expecting to glimpse into the intimate memories of the legendary Fount of Knowledge— or to find out that the man himself, now corrupted, is spying on him through his staff; a favoured pass-time while sealed away in the Silver Tree.

   Shadow Milk Cookie is grappling with the fact his replacement is everything he stands against, yet a reflection of everything he once was. It isn’t an unwelcome situation. His replacement has caught his eye in more ways than one.

   Mischief ensues.
