Ben Bril a'r Ddinas Ddirgel

Dim ond 14 oed ydy Ben Bril - mae Ben Bril a'i fryd ar achub y byd! Mae pobl yn diflannu cyn ailymddangos unwaith eto. Ond mae'r rhai sy'n ailymddangos ddim yr un fath a'r rhai sydd wedi diflannu. Dyma joban i Ben Bril! Mae Ben Bril a Brochfael y Ninja yn penderfynu gweld beth sy'n digwydd.

Ben Bril is a fourteen year old boy. He is very clever, but he's interested only in science and in saving the world! People keep disappearing and reappearing changed. Of course it's a door into another world,and Ben Bril and Brochfael the Ninja set off to find it. Ben Bril is ideal for anyone who is just starting to read on their own.
