As of this writing, the only sites from which to pre-order are Amazon and Apple. The Kobo link should be along later today or tomorrow. Sadly, even though other sites have shown that pre-orders work extremely well, most book distribution sites and webstore providers don't offer the option yet.
Anyway - Uncommonly Tidy Poltergeists will release on January 11, as planned. No changes there. If you do still want to pre-order, the Amazon and Apple links are below and MCB and I will be sharing the Kobo link as soon as it's up.
Thank you for your patience in this matter.
