What FIRE book would you recommend to get a wife interested in it

[Allan Guerra]

I am trying to get my wife interested in FIRE and REI, so I made a deal with her. I told her I would buy a kindle paperwhite for her if she would read the book I placed in the kindle. I want to place one of the most inspiring and convincing FIRE or REI ebooks ever in her kindle so she can decide to join my effort in achieving FIRE. The other catch to this is that she is learning English. I can provide her with a FIRE/REI ebook in English, but it would take longer for her to catch on. Therefore, I would prefer a FIRE book in Spanish. Does anyone know what the best FIRE/REI ebook is in Spanish out there right now? Thank you!
