I have just posted a list of short Spanish novels, written for students, on the Resources for Students
page. They are available for $6.00 each from www.BlaineRayTPRS.com
or from TPRS Publishing, at www.TPRStorytelling.com.
Some are at both sites, others may be found at only one. They are appropriate for beginning to intermediate students. Some are written in the past tense, some in the present, and a few are available in both versions under one cover! Take a look, buy a few, read them and then share with other students.
The SOU Bookstore will be getting some of these for you to buy soon.
