puzzle book

[notanidea]

can some suggest a good maths puzzle book for a 8yr old girl.she is good in maths but would like her to enjoy maths.

Not a maths puzzle book, but would she enjoy Murderous Maths - my 7 y/o loves them, they must be funny as she sits & giggles away at them . . .

she has read them and looks like she enjoyed it as well .Not sure how much she understood though
