Return of Rights and What Happens Next

I've recently learned that my publisher is closing up shop next year. This means that soon Wolf Creek and Spar will no longer be available. Within the next 90 days or so, I should receive the rights to the works returned to me and I'm left wondering what happens next.

Do I self-publish?

Do I resubmit to another publisher in the hopes that they will pick up a story that's already been published?

In either case, I need the return of rights documentation. Then I need to see about the rights to the final copy verses the original and the cover art.

This isn't the firt time I've had to deal with a return or rights when a publisher closes, but it is the first time that it's for published works. I hate to think of my two novels disappearing from the shelves never to be seen again. However, I am dreading that will be their fate. Either way, if you want a copy of their, pick it up now before it is no longer available.
