Literary escapism with the Doctor

I'm taking a little break from serious reading for some classic escapism.
"DOCTOR WHO AND THE KEYS OF MARINUS" is a novelisation by PHILIP HINCHCLIFFE of the fifth serial in the British television series "DOCTOR WHO," featuring the First Doctor (portrayed by WILLIAM HARTNELL).
It's a quick read -- I consumed half of it last night -- and a highly entertaining one.
The Doctor and his companions arrive on an extraterrestrial island under attack, and agree to help the solitary inhabitant find microchips necessary to restart a massive computer built to stamp out evil in that world.The quest leads to numerous adventures -- and plenty of opportunities for cliff-hanging developments.
I'll read something serious later. For now, I'm off on a brief literary escape.
