Has Anyone Read The Hammer and the Cross?

[JJ48]

I was reading some stuff about Tom Shippey, and apparently he co-authored an alternate history trilogy under a pseudonym. Is anyone familiar with this trilogy?

Hammer and the Cross trilogy on Amazon

And another book goes on my to-be-read pile... the co-author "John Holme" is Shippey, according to Wikipedia. He's listed on the print edition but not the Kindle. I'll bet his role was as historian as well as curmudgeon

Tom Shippey and Harry Harrison and Vikings??? That goes to the top of my wishlist. Right now.
