guide for "el camino de Levante"

Hello,

I'm looking for a guide for "el camino de Levante" (Valencia-Santiago), especially the part Valencia-Zamora.
It doesn't have to be too detailed, but the info must be up to date.
A small map of every stage with information about refuges, shops etc. will do the job.

I found the guide "De valencia a Santiago. Otra ruta a Compostela" from Amparo Sánchez Ribes. But there will be many others I guess.

Is there a guide that you would recommend?

thanks!
