The Hidden Treasure of Roseleigh Academy

This story revolves around the three siblings who just lost their grandfather. Their family is known to be very wealthy but kindhearted and humble. At the of reading the will, they were hesitant and depressed to come out of their rooms so the oldest had to convince them. They were all given books by their grandfather's assistant who was the one appointed to read the will.

The only girl sobbed as she remembered the memories of their grandfather reading books to them. Apparently, the siblings were only given books as their inheritance... Or so they thought!

There was a secret storage at the back of the book and a letter from their grandpa was hiding there! It seems as if he wants them to have fun on this treasure hunting adventure! Their inheritance were hidden in the school that their grandpa owns and they had to transfer to be real students rather than their homeschooling to have the chance to look for the treasure.

Unfortunately, an employee of their grandfather had leaked their secret out into the world so other people began intervening their supposed-to-be secret adventure.
