Visser (novel)
Visser is the third companion (Chronicles) book to the Animorphs series, written by K. A. Applegate. Within the continuity of the series, it takes place directly after the events of book #35, The Proposal, but is also in part a detail (chronicle) of the backstory of its narrator, Edriss 562, Visser One, whose host is Marco's mother Eva, and who is on trial for treason by the Yeerk Council of Thirteen in the "present" of the book.
