I confess, Doctor Who novels are my guilty pleasure. A bit (ahem) of a literary snob generally, I have been pleased with the writing in these books, and am generous in my ratings of them, because I find them so enjoyable. But this one broke me. Generally well written, the characters are captured well and the story was clever. But exclamation marks only work in dialog, generally speaking. Cheerleader enthusiasm and exclamation marks do not have a place in narrative, no matter how exciting the circumstances. So, while I recommend Dr Who books to the fandom, I want to be sure you all know this style of writing is not typical.
