"Opal has almost done it all -- fought monsters, protected people from pillagers, and even defeated the legendary Ender Dragon! But that's all in the past. Now, Opal has hung up her adventuring hat and is living the life of a happy crafter, far more likely to build a bed than to fight a Wither. In fact, Opal has decided that her time is best spent building her dream manor outside the very village that displays the Ender Dragon skull she brought back from the End! Meanwhile, Opal's sister, Lisa, is at the beginning of her own journey. She's ready to be a hero. Just ask her. Or don't. She'll tell you anyway. She knows every single story ever told about her sister and probably about a few other heroes as well. She admires Opal immensely -- always has. But now it's her turn for an adventure. And that adventure might be bigger than she could ever have imagined. One day, a traveling adventurer named Braun arrives in town, claiming he knows how to defeat the Warden -- a fearsome mob that not even Opal has bested. Lisa jumps at the chance to join Braun on his epic quest, and Opal reluctantly agrees to accompany the duo -- only to protect her sister, of course. But along the way, Opal might just rediscover her love of adventure, and realize that it's even more fun when someone else is there to share in the story." -- Provided by publisher.
