Esen's back And the dear little blob is in trouble, again.

Things began so well. She and her Human friend Paul Ragem are ready to celebrate the first anniversary of their greatest accomplishment, the All Species' Library of Linguistics and Culture, by welcoming his family back. He hopes. Having mourned his supposed death years ago, understandably, feelings are bent.

Instead, they've unexpected guests, starting with an old acquaintance. Paul's father has gone missing under dire circumstances.

Before he can convince Esen to help him search, a friend shows up to use the Library. A crisis on Dokeci Na is about to explode into violence. To stop it, Evan Gooseberry needs answers. Unfortunately, the artifact he brought in trade holds its own distracting secret. A touch of very familiar blue. Web-flesh.

The race is on. Paul, to find his father. Esen, to search for a mysterious legacy while helping Evan avert an extinction. What none of them realize is the price of success will be the most terrible choice of all.
