10 Final Onyx Storm Predictions That I’m Officially Locking In, One Week Before The Next Fourth Wing Book Releases

There are several convincing theories as to what will happen next in Yarros' Onyx Storm, but I think my predictions are most likely to come true.

In the U.S., the start times for these events align with the book’s midnight release on the East coast. Therefore, those attending release parties in other time zones can get their hands on the book earlier. For example, Barnes & Noble’s Los Angeles release party, which Yarros will be present for, will hand out books at 9 p.m. PT (viaBarnes & Noble). The times may differ in other countries. In the U.K.,Onyx Stormwill be available at 12 a.m. GMT. Those attending midnight release parties should check the time listed online for their event.
