I would go with Alan Watt's -- give both The Book and The Way of Zen as a combo perhaps. Classics, especially for their humor and enthusiasm. Likely available in Spanish.
More scholarly but still readable is the short monograph What is Zen? by R.H. Blyth which is actually volume 1 of his Zen & Zen Classics. Not sure about availability of that in Spanish.
