Best resource for £15 at Waterstones...!

[Lovemedo345]

I have a £15 voucher for Waterstones, would like to invest in my mental health, was thinking maybe book about stoicism and a blank journal to write down thoughts... But open to any good ideas or recommendations anyone may have, either a book in any category or something I haven't even considered! Many thanks in advance
