"Afterward" is praised for being an amazing story that revolves around two families who get a second chance with their loved ones they thought were lost forever due to an abduction. It's seen as a dream ending for families who have experienced their own abduction stories. The return of Ethan and Dylan, the abducted children, seems like a perfect resolution, but the story is portrayed as just beginning.

Jennifer Mathieu is commended for her excellent storytelling, particularly her ability to weave together the "before" and "after" narratives. While the book doesn't dwell extensively on the past, it does provide enough context through vivid flashbacks to paint a poignant picture of what the two boys endured before their rescue. The reviewers mention that the subject matter is handled with sensitivity and is generally suitable for a PG audience, although it could be triggering for some readers.

Readers express how they were deeply engaged in Ethan's healing journey and were satisfied with the overall ending of the story. There's a desire for a more definitive resolution for Dylan, but it's acknowledged that the book's length may have limited the exploration of his healing process.

One reviewer, in particular, appreciates the book's portrayal of trauma and recovery. As a public school teacher working with students who have experienced trauma, they emphasize the book's realistic and sensitive depiction of trauma sufferers, as well as its positive portrayal of therapy and the healing process. They believe the book has the potential to resonate with vulnerable students.

The reviewers also highlight the book's ability to tell a compelling story about the aftermath of a disaster, focusing on the characters and their relationships, which they found highly engaging.

However, there are mixed feelings mentioned in one of the reviews. While the book is generally considered good, it's not recommended for those seeking accurate representation of autism due to concerns about the author's citation of Autism Speaks, an organization criticized for its handling of autism-related issues. The review suggests that readers interested in autism representation should seek out alternative sources like the Autism Self Advocacy Network.

In summary, "Afterward" is praised for its engaging storytelling, depiction of trauma and recovery, and the relationships between its characters. However, it receives criticism for its portrayal of autism and the author's choice to reference Autism Speaks as a source for information about autism.
