I'd strongly recommend putting some description of what this actually is. I feel like I should know within the first minute or so of being on a site what exactly the site does, and I can't tell that by your website.
Very cool idea. Not sure I could tell exactly what it was when I landed though.<p>Interface wise the expand to full screen was so small it ended up looking like an X (aka close). So I clicked it and it annoyingly went full screen. Not bad just something that I noticed.<p>good job.
This seems like a step in the wrong direction when it comes to the online reading experience.<p>- can't save it for offline reading<p>- can't scroll, have to scroll and flip through fake paper book<p>- can't search inside the book<p>- resizing text can cause pages to be cut off<p>Why would I read it on bubbl.in when I can read it like this?

On my MBP 13" non retina book pages do not fit the screen, so you must go up + down at every page, which is frustrating. You should reflow text so that it fits a screen without scrolling
