Mockingjay marks the conclusion of the widely popular Hunger Games series. This last book follows Katniss Everdeen, who, after being appointed by the rebels as the symbol of resistance, becomes "The Mockingjay." But her newfound leadership role brings with it great risk, and Katniss's battles with mental health issues become even more significant as a result.

The book is a clear departure from the previous two installments in terms of tone. It's raw, emotional, and deals with political and strategic themes while also tackling mental health issues such as depression, anxiety, and the trauma of war. The extreme violence in some parts of the book makes it more challenging to enjoy, but it effectively portrays the devastating effects of war on both sides.

Despite the book's darker tone, I enjoyed reading it as the conclusion to the trilogy. It was able to tie everything together, and it was rewarding to see Katniss grow out of her young adult persona and into adulthood.
