This is ‘Catastrophea' by Terrance Dicks, published in 1998 as part of BBC Books' 'Past Doctor Adventures' range, featuring the Third Doctor and Jo Grant.

The book has been read but is in generally good condition, especially for an item of this vintage.

I have a positive feedback rating of 100 per cent, so you can buy with confidence. I can combine postal charges for multiple purchases.

Thanks for reading this.
