KOBO ebooks (drm protected) readers for linux

I am willing to purchase some ebooks, but I find them only 
in the "KOBO" reader (drm protected) file format.

Since I've never used them, does anybody know if there is a 
foss READER for linux (no kindle, smartphone or else) ?

Or even better : would some other reader (okular, djvu) be 
able to dodge the DRM and read them ?


I'd not want to buy sth I could possibly be unable to read :\

tnx in advance
