ANIMATE USA has announced on Wednesday that it is releasing "Pet in Love," a bonus Pet on Duty boys-love story by Nase Yamato, exclusively as an electronic book on the Amazon Kindle Store. ANIMATE USA is also releasing Youka Nitta's Sound of My Voice Golden Goose Part 2, Shiuko Kano's P.B.B. Play Boy Blues - Act 2, and Makoto Tateno's See You in the School of the Muse Volume 1. (See You in the School of the Muse is a full-length book, but unlike the other releases this month, it is in Japanese.)

ANIMATE USA is the American arm of Japan's ANIMATE retail chain for character goods. The company already released the main Pet on Duty book and the first installments of Sound of My Voice Golden Goose and P.B.B. Play Boy Blues on the Kindle Store. Broccoli Books' Boysenberry boys-love imprint had previously released Pet on Duty in print, and Central Park Media's Be Beautiful boys-love imprint had previously released Sound of My Voice and P.B.B. Play Boy Blues in print.

Kindle Books can be read on Amazon's own Kindle devices (in several different versions), a free App for iOS, Android, and Blackberry mobile devices, and the free Kindle application for Windows and Mac OS X operating systems.
