From publisher blurb:
Nine new psionic monsters await within the pages of this part of the Psionic Bestiary!
From inconspicuous creatures like the mechanical phrenic conduits and the iniro plant creatures, to the sinister Marked Ones, to the downright vicious mindrippers and zurami, this release has a variety of new psionic creatures for use in your games.
In 2011, Dreamscarred Press held a contest for a psionic bestiary. The monsters from that contest are being released in a series of releases and will ultimately be compiled into a single psionic bestiary book.
