The 4th book in the series didn't disappoint.
I still adore Whyborne and this book made me like Christine even more and Griffin is a perfect gentleman as always.
I would love to know more about Griffin but alas the series are written in a limited 1st person point of view. The short story Eidolon gives a glimpse of Griffin pov but it isn't enough. :(
The adventures of Whyborne and Griffin in London that Whyborne refused to think about are written in a free short story Remnant by K.J. Charles and Jordan L. Hawk
Weak spoilers below.
An urgent telegram from Christine summons Whyborne (and Griffin) to Egypt.
Whyborne is kissed by a beautiful woman
attacked by ghuls & gets splattered by blood
practises more magic
gets a pet camel
And much more!
