Minnan no Nihongo online versions?

Hey guys,

I started studying Japanese about a year ago.
I used Anki for vocabulary, but I am still pretty lost in Japanese grammar. Now I bought Minnan no Nihongo and I love the books. But sadly I spilled a drink on my text book and I really can’t afford a new copy. Do you guys know where I could get a online copy of my book? Maybe I could get a online copy somewhere cause I actually bought the book?

I’d really appreciate any help!
