My favorite book is The time travilling cat and the aztec sacrofice. it is about a cat called Ka, who goes time travilling. Every time she goes time travilling she leaves behind a grey, cold statue. Topher, who owns Ka, is comfused the first time she leaves. The aztec sacrofice bit is because when Ka goes time travilling she goes to the aztec times. Around 1645. When they get there Topher is working for Cortes the spanish army leader. Half way through the book topher finds Ka in the hands of the aztec god Bastet. There are 3 priests.
