india

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

'hot location' is the definition.
'India' can be an answer for 'location' (India is an example). I am not sure about the 'hot' bit.

'written in certain diaries' is the wordplay.
'written in' indicates a hidden word.
'INDIA' is hidden in the letters of 'certain diaries'.

Can you help me to learn more?
