Transformers: Prime is a multi-volume adaptation published by IDW Publishing of the Transformers: Prime cartoon. The first volume was published in April 2011. Each book contains an adaptation of multiple episodes in the form of screen captures arranged in a comic book format.
Volumes three and four, presumably covering "Masters & Students" through to "Convoy" were solicited around the same time that the first two were released. Neither of them eventuated, and the series stalled until over a year later when it skipped the rest of the first season and started on season 2.
