UK: Personal finance book for a twenty-something
As you are in UK, you should think in terms of Tax Free (interest and accumulated capital gains) ISA type investments for the long term AND/OR open a SIPP (Self Invested Pension Plan) account where you get back the tax you have paid on the money you deposit for your old age. Pensions are  the best bet for money you do not need at present while ISAs are suitable for short term 5 years plus  or longer.
