Katherine Woodfine does similar kinds of crime books. The Taylor and Rose Secret Agent series and the Sinclair Mysteries.

My 10yo daughter just read and enjoyed the Percy Jackson series, and we've just got her the Magnus Chase series; and Trials of Apollo series by the same author (Rick Riordan: www.rickriordan.co.uk/ )
They seem to be about Greek gods

Lady Grace mysteries (Elizabethan)
A Wizard of Earthsea
The Dark is Rising
A Series of Unfortunate Events
Edge Chronicles
