There have been some hiccups with Wicked Doll, therefore it will be delayed until June. If you ordered through Amazon, you should have received an email stating that the pre-order was canceled.

New release date: June 15th, the latest.

Nevertheless, you can pre-order Wicked Doll through the other online retailers except for Amazon:

iBooks | B&N | Kobo | Google Books |Direct

I apologize for any inconvenience.
