This looks like a great re-issue of a hi-lo series, with brand new, very appealing covers. Take a look at the link below, where you can see the covers and read excerpts from a number of the titles. (towards bottom of webpage) Good for reluctant readers and ESL students.
Artel in Burbaby is selling them for $ 4.50 CDN each (w 20% discount for schools)
There are some bundle deals as well. (But make sure you get the new covers, and not the older ones. https://secure.arteleducational.ca/catalog/index.php
