I must admit this was the project I had the most fun with. Since I now was comfortable with both Meteor / Mongo and with React, it just all came together smoothly. This app has everything the challenge required and more like owner opinion that each owner can contribute to, book preview and a book swap feature. I tried to add every function I could have thought of. The site uses no styling framework like bootstrap, it is all done "by hand". Here is where I started really looking into color palettes and design principles.
