Dark Waters of Time [PDF ebook] 

The Dark Man must take the girl to the pool of magic water, where she can see into the past. Only she can tell him where the Golden Cup was last hidden. This book is part of the Dark Man Series, a range of books for emergent teen and adult readers. With only a limited vocabulary, these gritty and mysterious books pull readers into the tense storyline. The sinister atmosphere and strong black-and-white illustrations ensure that the book appeals to older readers and isn’t patronising. This is one of the shorter stories in the Dark Man series focusing on the top 100 high frequency words.
