The Origin Stone [EPUB ebook] 

Emily Renzi thinks she’s going crazy. After her parents move to a quiet village, she senses that something is off about the house they’re living in.
Dreams of strange creatures invade her sleep, and mysterious shapes appear in the garden. Confiding in her older brother, Ru, they research the house’s background and find out that a scientist disappeared there during World War Two. Afterwards, sightings of strange creatures were whispered around the village.
Could the creatures in Emily’s dreams be the same ones and if so, what do they want from her? Struggling to piece together the truth, Emily soon understands that monsters come in many forms.
