Identifying the Author's Tone in a Literary Critique

Read the following excerpt from a literary critique:

'In her latest novel, the author weaves a complex tapestry of emotions, exploring the depths of human despair alongside fleeting moments of fragile joy. The prose is imbued with a poignant melancholy, compelling the reader to ponder the transient nature of happiness. As the narrative unfolds, you feel as if you are traversing through a fog, where every revelation carries a weight that echoes long after the page is turned. This intricate storytelling not only reflects the painful realities of life but also illuminates the beauty found within it, suggesting that joy and sorrow are indelible companions on the journey of existence.'
