I tried it out quickly and have two suggestions: 1) Pre-fetch the data such that the page can be immediately rendered when opening a new tab. Seeing a 1+ second loading animation for something done as often as opening a new tab introduces unnecessary friction. 2) Retain a history such that the user can see which books they have had shown to them so they don't suddenly lose a suggestion by closing a tab.
