Your mission, should you choose to accept it, is to read this book in two months or it will self destruct:
Argentinean independent publishers Eterna Cadencia are publishing an anthology of new Latin authors using special ink that disappears once it comes in contact with sun and air, completely disappearing within 2 months time after opening the book. This makes for an interesting approach to motivate book buyers to read books more promptly, giving first-time authors the attention they need to survive:
Which also means people who enjoyed these struggling new authors cannot pass the book on to friends or come back and read them again. Not to mention the negative pressure of being forced to read it in a certain time.
I predict this gimmick will fade away inside two months.
