Although Carter and Sadie Kane are siblings, if they were standing in the same room you would never know. Not to mention the fact that Sadie and Carter have been separated ever since their mom died, Carter going with their dad to study Egypt and Sadie living with their grandparents in England. When their dad takes Carter to see Sadie and brings them to the British Museum, they see that their father wants more than ever to bring their mom back. When their visit to the Rosetta Stone goes wrong and Carter and Sadie's father is imprisoned by a strange creature, they realize just how much they don't know about Julian Kane. Toss in a few monsters, some angry Egyptian Gods, and a good dose of Egyptian magic, and suddenly Carter and Sadie are on a quest to get their dad back without getting killed themselves. This book is amazing and I totally recommend it to anyone who loves fantasy, mythology, and adventure! Rick Riordan is an amazing author and paints pictures with his writing, allowing the reader to be transported into Carter and Sadie's world. I would give this book 5/5 stars and recommend it for ages 10+!
