Sometimes authors fail to deliver when they write outside their established series (the Merrily Watkins novels in Rickman’s case). However, in The Bones of Avalon Rickman does a brilliant job, jumping back to Elizabethan times.
As with the Watkins series, there is a strong hint of supernatural mystery without falling into out an out fantasy. Dr Dee, an advisor to Queen Elizabeth (and based on a genuine historical personage), becomes involved in seeking out a mystery that is rumoured to go back to Arthur and Merlin.
I have no doubt that this deserves/ 5 and I will now be watching keenly for a return of either Rev. Watkins or Dr John Dee!
