Good to hear from you down under. Yes all is well here.
To answer your question ; I have not seen the book yet but knew it was in the works some time ago. Elizabeth contacted me for some information in the past so I knew it was being worked on. She told me yesterday via email that it has now hit the book stores.
I cannot yet comment on the exact contents of her work but know much of it is about her grandfather's life in the NMP/NP, having arrived in Pietermaritzburg and joining up about a month after Isandlwana. In fact his draft of recruits was specifically brought from England by Dartnell to make up for the attrition in the NMP suffered as a result of the battle.
Elizabeth Thom, the author, is George Mardall's granddaughter and is a member of this forum, so can be contacted via this medium for more information.
