School Library Journal Review

Gr 8 Up--The many depictions of grief shine in Wallman's latest mystery-thriller. Skye's life has changed a lot since last summer. Not only did her sister die but her mom and dad have also spent so much money trying to treat her brother's heart issues that they had to sell their home and move. Plus, Skye can't swim anymore and hasn't kept in touch with her friends. A summer camp for teens who have lost loved ones might be Skye's chance to change all of that. Then, she starts receiving mysterious messages from an impossible source--her sister. As Skye tries to figure out what's really going on, something even more sinister is happening at camp, and Skye will have to face her fears to prevent even more death. This story focuses on Skye's experiences with the other campers and coming to terms with her sister's death. The mystery-thriller elements of the story are lacking; the mystery behind the messages Skye receives lacks urgency and comes to a predictable end. Meanwhile, the pacing of the additional thriller plotline is very rushed and only becomes important in the last few pages. Readers who like stories about grief will enjoy reading about Skye and the other teens at the camp, all of whom are presumed white except Brandon, who is half-Black. Those who are looking for a mystery-thriller may be disappointed. VERDICT Not a must-buy for mystery-thriller collections, but readers who enjoy camp stories, like Emma Lord's You Have a Match or Jessica Goodman's The Counselors, or stories about dealing with grief, like Jandy Nelson's The Sky Is Everywhere, may want to pick this up.--Alison Glass

Booklist Review

Skye Colton arrives at a summer camp for bereaved teens, trying to forget about how her older sister, Luisa, died last summer. While participating in a therapeutic activity, she sends a text to Luisa in their secret chat--and gets a text back in response. Skye is momentarily elated until she realizes that it cannot be her sister. It must be someone she knows, so everyone is a suspect. The story is a good reflection on the grieving process and how people walk through the steps in different ways. Readers may find it disappointing once they realize that what initially seems to be a mystery about who killed Luisa morphs into a lower-stakes question about the anonymous texter. Despite this, the protagonist's fellow campers have well-developed backstories on why they are there, helping flesh out the story. The ultimate strength of the work is Skye's self-reflection and steps toward redemption. Recommended for readers of contemporary fiction who prefer thoughtful and kind characters, with side tangents of romance and light mystery.

Kirkus Book Review

An English teenager receives texts from someone claiming to be her deceased older sister. Eager to distance herself from the traumatic death of her 18-year-old sister, Luisa, last summer, Skye Colton was excited about being offered a full ride at a summer camp, thanks to the charity Bereaved Aid for Kids. But she's apprehensive as it nears and she realizes that the other campers have their own stories of loss: anxious Fay, rebellious Danielle, perceptive Brandon, and domineering Joe. Interspersed throughout the present-day camp storyline are flashbacks of Skye and Luisa's relationship from the year before: Skye, trying to reconnect with her sister, who was involved with flashy new boyfriend Nico, eagerly offered to assist with deliveries for a "nutrition supplement business" Luisa and Nico were involved in. Skye's naïveté and the ominous direction Luisa's choices were taking her come through clearly. Now she knows that the messages on the MessageHound app can't possibly be from Luisa. Suspicious that someone at camp is sending them, she becomes determined to find out their identity and motives. Skye's inner turmoil is strongly sympathetic, and the flashbacks and earlier timeline heighten the intrigue while cleverly keeping readers in the dark about what exactly Skye knows about her sister's death. Skye's investigations reveal insights into the other campers, creating an engrossing narrative that leads to an unexpected, nail-biting conclusion. Most characters read white. Brandon has a white mother and Black father. Suspenseful and compelling, with authentic representations of loss.(Thriller. 14-18) Copyright (c) Kirkus Reviews, used with permission.
