Mae’r stori i fod i ddod i ben.

Gwnaeth Simon Snow bopeth yr oedd fod i’w wneud. Curodd y dihiryn. Enillodd y rhyfel. Syrthiodd mewn cariad hyd yn oed. Nawr daw’r rhan dda, iawn? Nawr daw’r hapusrwydd am byth…

Felly pam na all Simon Snow ddod oddi ar y soffa?

Yr hyn sydd ei angen arno, yn ôl ei ffrind gorau, yw newid golygfeydd. Mae ond angen weld ei hun mewn goleuni newydd.

Dyna sut mae Simon a Penny a Baz yn penderfynu dreifio car vintage, ar draws Gorllewin America. Maen nhw’n cael trafferth, wrth gwrs. (Dreigiau, fampirod, pethau pen-sothach gyda gynnau.) Ac maen nhw’n mynd ar goll. Maen nhw’n mynd ar goll gymaint, maen nhw’n dechrau meddwl tybed a oedden nhw erioed yn gwybod lle’r oeddent yn mynd yn y lle cyntaf.

The story is supposed to be over.

Simon Snow did everything he was supposed to do. He beat the villain. He won the war. He even fell in love. Now comes the good part, right? Now comes the happily ever after…

So why can’t Simon Snow get off the couch?

What he needs, according to his best friend, is a change of scenery. He just needs to see himself in a new light.

That’s how Simon and Penny and Baz end up in a vintage convertible, tearing across the American West. They find trouble, of course. (Dragons, vampires, skunk-headed things with shotguns.) And they get lost. They get so lost, they start to wonder whether they ever knew where they were headed in the first place.
