Cover blurb
This is a story about Winter...

As the Doctor becomes involved in affairs aboard the Federation Starhip Nepotist, his old friend Iris Wildthyme is rescuing old ladies who are being attacked by savage owls in a shopping mall.

And, in a cat's cradle of interdimensional Corridors lies the Valcean City of Glass, whose king Dedalus awaits the return of his angel son and broods over the oncoming war...

This is another in the series of original adventures for the Eighth Doctor.
