The Mysterious Bookstore

You and your friend Arthur have searched for the mythical Tree of Life your entire lives. Just hours ago, Arthur called you in a bundle of excitement saying he found the secret entrance! But the address he sends you turns out to be...a bookstore? It's nighttime by the time you arrive, not a soul in sight, but you try the door anyway. And it opens! Curious, you head inside, unsure of what you'll find but feeling this bookstore is a lot more than it seems.
