Worst app update ever

After updating to the current version of Free Books the app is unrecognizable! My library, which had at least a dozen books in it, was wiped out ... gone. The search function rarely works now, and the audiobook popup ads are unbearable. Even the look and feel of the classic books was degraded. You guys took a solid, decent app and literally destroyed it. Why??
