This book is everything I want in a Doctor Who novel:

[Jack] ‘Mrs. Knife-Attack might be waiting. I shot her a few times but she didn’t seem as impressed as she should have been.’

[Doctor] ‘Probably not. She’s been dosed up on mutagenic revivifacation energy for a while.’

Rose looked at Jack. ‘What’s he on about?’

‘MRE,” Jack said. ‘Like, life force.’

‘Then why not say “life force”?’ Rose said.

‘Look, I didn’t write the manual,’ the Doctor protested.

Deviant Strain by Justin Richards. Nine, Rose and Jack. Nine being clever, Rose taking care of herself and Jack being bamf. Fantastic.
