The time had come to choose which of the old covers we wanted to replace first. Traps won the 'contest' hands-down.
The one on the right is what we replaced - no words are really necessary to convey why we chose to replace it - and yes, others will be replaced as soon as the funds come in.
In the meantime, the cover is all that changed for COS 5. I haven't modified and combed through the old manuscript at this time to correct any other errors that may exist. Hopefully, there aren't too many.
