Libby, by OverDrive

The UI is streamlined, but it's chugging under the hood. My Surface Pro 3 CPU is at 50-60% with nothing else running and the whole computer is overheating!

Loaded it on as soon as I got Win10 on my phone and downloaded the books I already had checked out on my Android tablet. Opened the book I am currently reading from where I left off on the tablet. It may or may not sync across systems or devices, I don't know. I expected to have to find my last spot. But when I read for a bit and then backed out of the app, THE BOOK WAS BACK AT THE BEGINNING. So I found my new place, read, exited, came back, and saw the cover page yet again. Nope. Done. LOVE the Overdrive app on Androids, and even the previous version on Windows, but that's it. I'm not restarting my books randomly whenever the app decides it needs to go back to the beginning.

App constantly crashes, over half the time when I re-open my book it puts me back at the beginning, and it deletes my bookmarks (which happens about once a week). Very poorly done app. I recommend using the web reader on the overdrive website if you don't need offline access.
