Freedom Baird's islands book

I want to edit an e-book, a scientific textbook to be distributed on the Kindle tablet to be exact. The book is written. For that I used LibreOffice.
It comes complete with index, drawings, pictures, formulae and its present look and feel is no different from the majority of scientific text, you might be accustomed to browsing. I need advice for the next step, which consists in making this digital pile of data suitable for an e-book.. with a slight twist. The e-book should allow for:
— picture zoom-in in pop-ups on screen
— allow in-text basic interactivity, e.g. when in a exercise, multiple answers are proposed, each answer when clicked should display "Right" or "Wrong" (for instance).
Can you recommend, if not a commercial package that allows such features right out of the box, then at least and preferably open-source technology needed for me to achieve what I want ? I am willing to get down to moderate programming to use your suggested solution. I am conversant in C, C++ and getting there with Python.

GitBook is a modern publishing toolchain. Making both writing and collaboration easy.
