All the absolute are worth a read, particularly Are bones are scattered. The British in India 1825 - 1857 by John French in the Foundry series is pretty good. For uniforms I’d swop if for all the Ospreys and it has every thing from Bhurtpore to the Mutiny inc 1st Afghanistan the Sikh wars and all sorts of more obscure actions.
It’s not an overview of the mutiny as such but it’s packed with detail on the particpents, uniforms, colours etc and also has quite a few battle maps, OOBs etc I should have checked before I posted but I think there is a Kindle version given the high price for hard copies
