Rainbow Dash has read the entire Daring Do book series twice already. However, when she goes back to the library to re-read the series for the third time, Twilight informs her of a new author who just came out with a new Daring Do book. Of course, Dash can't wait to read it. However, when she does start reading it, she finds that she's in for the adventure of a lifetime. (Yes, the Doctor was a pegasus in one episode and yes, this story is based off of the DW episode "The Angels Take Manhattan. Shut up.)
