How do I read volume 3?

How do I read volume 3 with heavens story? has the third chapter came out. .I'm so confused how to use this app . .I just want to finish volume 3 the suspense is killing me I love these books! !!

At this moment I do think that he is the man from her dreams... Can't wait to find out!!!

I love the idea of heaven and Zarin together... Plus if possible the bloodline shld still be from heavens side

I can't stop reading !!
