Taking My Reincarnation One Step at a Time: No One Told Me There Would Be Monsters! Volume 2 [EPUB ebook] 

One night, Sara dreamed of a goddess—or something like it—who granted her a new life. She awoke in the body of a child and was greeted with wyverns, wolves, and all other sorts of monsters the very moment she opens her eyes. Thankfully, a Hunter named Nelly came to her rescue, and they’ve been enjoying fun-filled and peaceful life together ever since… Or rather, they were until the day Nelly went into town and didn’t come back. Sara resolves to leave home and look for Nelly in the town of Rosa, where she makes a friend, joins the Hunter’s Guild, and waits for Nelly to return. All is going well until the arrival of a group of knights throws her new life into a new turmoil! Will Sara and Nelly finally be reunited?
