Children’s book with fair distress call given to Conservatives (4,2,7)

I believe the answer is:

just so stories

I'm a little stuck... Click here to teach me more about this clue!

'children's book' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'fair distress call given to conservatives' is the wordplay.
'fair' becomes 'just' (Synonym).
'distress call' becomes 'SOS' (an SOS message sent in an emergency).
'given to' means one lot of letters go next to another.
'conservatives' becomes 'Tories' (informal term for the Conservative Party).
'just'+'sos'+'tories'='JUST SO STORIES'

'with' is the link.

Can you help me to learn more?

(Other definitions for just so stories that I've seen before include "Work for kids" , "work of fiction" , "book for children" , "Book by Kipling" , "Accounts for children" .)
