With the Black Hole Radio series, Ann Birdgenaw is writing light science fiction adventures for young readers. In the series, three grade-school-aged kids get pulled into cosmic wormholes by the strange workings of the titular radio, which belonged to the grandfather of one of the kids. To keep things moving and to keep the adventures light, Ms. Birdgenaw has set things up so that aliens have given the three children mild esp-powers. One of the kids, Celeste, was also given a bit of telekinetic

This book feels much shorter than the previous ones in the series; this one feels like a repeat and rushed. I barely know much about the world or planet, and the ending leaves many questions because it is majorly destructive. At this point, I'd expect that readers must have read the previous books, so seeing more character developments and backgrounds in their real-world would be great, like the previous books, because they are almost non-existent here.

"Beep, beep, beep, beep," sounds the radio, and Hawk, Celeste, and Matt are off on another adventure through the black hole. This time they find themselves in an alien, cavernous labyrinth, as they try to locate a missing classmate and the way out. Along the way they meet some aliens and help find a solution to an injustice.

The long awaited fourth book in my series, Black Hole Radio, is out and it's definitely the darkest one so far. Hawk, Matt and Celeste have to go through the worm hole radio again! This time to save Big Mikey who was snooping around the UBSS clubhouse and disappeared. How can the friends be sure they'll go to the same planet as Mikey to bring him home? Hawk has the solution: his grandpa's journals will help them. But who will help Hawk and his buddies when they end up lost in the caves of Labyri

This was a very exciting addition to the Black Hole Radio series. Hawk, Matt, and Celeste are three friends who have been on adventures through space together before, with the help of Hawk's radio. His grandpa who died before the series began, left it to him, and it has powers that can transport him and his friends through space to different planets. In this book, Hawk is stuck with Big Mikey as his science project partner. Big Mikey happens to be the school bully. When Mikey comes over to work

Another Fun Adventure in a Whole New World!
Black Hole Radio: Labyrinthia was a fun, quick read and another great addition to the series! I love how each book takes the kids to a completely different world—this time was no exception, with a creative and unique setting that made the adventure exciting from start to finish. This is my second book by Ann Birdgenaw, and I continue to be impressed by how imaginative and kid-friendly these stories are. A fantastic series for young readers who enjoy fas ...more

Fun continuation of the worm hole radio. Hawk has to be science buddies with the class bully but when Big Mikey disappears into the Black Hole Radio the friends have to go after him. They go to planet Labyrinthia and learn a whole lot about caves and child slavery. The mine bosses are forcing alien children to dig for crystals that provide energy for the planet. This is not cool but Wolfie and their new aliens friends are super cool and they're in for an exciting escape when Hawk, Matt and Celes

My son loves this series and he's excited about book 4. Hawk and his friends are playing basketball and working on science projects ... that is until Big Mikey accidentally gets sucked into the radio. They go in after him to the creepy planet Labyrinthia. Which, like the Pied Piper of Hamelin, has used music to lure all the children in the village into the deep, dark caves to dig for energy crystals. We really liked the big wolf dog "Wolfie" who helps them get the alien slaves out of the caves a

Labyrinthia is an enjoyable adventure book for youngsters. The writing shines when the author tells the story with actions, such as when Celeste uses her telekinesis to save the team: “I flounder around to get my balance as we grab hands and rise towards the ceiling . . .” There are also moments of concise poetry, like “We follow Wolfie’s tail like a waving flag.”
The writer also addresses worthy subjects. Child labor (slavery, essentially) is the primary issue for the story. Birdgenaw knocks off ...more

Hawk, Celeste, and Matt are at it again. From school science projects, playing on the basketball team, and dealing with bullies, these kids keep busy, but they have more to worry about than kid stuff. The radio in the garage is an interdimensional portal and sucks them into that portal at random times. This time, the kids go to a planet called Labyrinthia where alien children are forced to work in the mines. As always, it’s time for them to save the day.

Themes of friendship, bravery, and loyalty.
Hawk, with his best friends Celeste and Matt, are reluctant heroes with powers and a gateway to other worlds. Their wormhole device sets the adventure and the special abilities grant the kids ways to resolve conflicts without fighting.
The first person narrative and present tense keeps the action zipping along. That coupled with the illustrations put me in mind of the old CYOA stories by Bantam Books, though the Black Hole Radio series is aimed at an aud ...more

This fun book, written for children ages 8-12, is part of a series and includes science references, a nod to A Wrinkle in Time, the Twilight Zone, black holes, and other topic-starting ideas and themes for parents who like to read with their kids. The friendship between the group of kids, Hawk, Celeste, and Matt, reminds me a little of Stranger Things without the scary upside down. The dialogue between the kid characters didn't seem realistic at times, especially if you've read other authors in

Grandpa's Legacy
This is a breezy, wholesome novel for kids with cool illustrations. It is certainly not necessary to read the others in the series because each stands alone and is easy to follow, but I suspect the target audience will want to read all in the series. In this one we even get a primer on popcorn and there is a great science dictionary at the end.
There's even a bit of social (in) justice thrown in concerning child labor in mining but I will leave that for another discussion.
