What the River Knows was a fascinating story and an enjoyable reading experience. I didn't want to put it down.

The author skillfully blurs the lines between reality and fantasy, crafting a narrative that is both authentic and imaginative. The world of What the River Knows was written with meticulous detail. 

Through the perspective of protagonist Inez, the narrative unfolds a thrilling treasure hunt while uncovering the mysteries surrounding her parents. Whit's perspective is also included in small sections. The inclusion of historical figures such as Cleopatra adds depth and intrigue to the narrative. There are more historical figures and events included that are important to the story. 

All of the characters were distinct and offered value to the story, enriching the narrative with their unique personalities and contributions.

One of the novel's strengths lies in its incorporation of multiple languages and Egyptian mythology, adding layers of complexity to the story. While prior knowledge of these elements isn't necessary, it enhances the reading experience for those familiar with them. The gradual introduction of these cultural aspects complemented rather than overshadowed the plot, which maintained a perfect balance between engagement and accessibility.

It's important to note that the novel contains depictions of gun violence and graphic murder. Short scenes depicting misogyny are also in the story, albeit brief and conveyed through dialogue.

What the River Knows was left open, with an intriguing reveal, for the next installment, Where the Library Hides.
