The English language version of Le monde de Milo - Tomes 5-6 (Dargaud).
From the publisher:
The village's tranquility is once again threatened as a mysterious girl is found floating in the lake, one who has a strange connection to the wild brambles that climb into the sky, and the terrible monsters that are climbing down to terrorize the land! It's now up to Milo and Valia to embrace their innate magical powers to save the land!
A beautifully illustrated, family-friendly, magical adventure in the vein of AMULET, THE WIZARD OF OZ, etc. The third of three self-contained story volumes.
