Hungry for sci-fi with real science? Then this family-friendly "Geek Fest" cross between Star Wars and Lost in Space is for you!

Written by a physicist with 20+ yrs NASA experience, this box set contains the four full-length novels that comprise the Star Trails Tetralogy PLUS The Compendium, the series' companion volume with a glossary; detailed information about the Cyrarian planetary system; and chapter-linked discussion ideas, lesson plans, & project suggestions for parents & #STEM educators who use this suspenseful series to stimulate interest in physics and engineering.

• Beyond the Hidden Sky (Vol. I) Laren Brightstar knows refusing to work for Augustus Troy makes him a target. Being reassigned as chief terralogist for a planet on the other side of the galaxy seems the perfect solution. Getting there, however, isn’t. Not with a teenage daughter like Creena. She’s intelligent. She’s a rebel. And now she’s missing. In deep space. Was it an accident? Or abduction? Either way, he has to find her. Before his nemesis does. And somehow he knows life will never be simple again as increasingly suspicious circumstances scatter his family across the galaxy, each wondering if they'll survive long enough to be reunited ever again.

• A Dark of Endless Days (Vol. II) Cyraria's lethal weather extremes max out Laren's engineering skills, but his family will perish unless he builds a heat exchanger (air conditioner) to keep their meager ballome at livable temperatures during Opposition. Before its completion, however, old debts come due, leaving his son, Dirck, to complete the task. How can he possibly do so with no money & limited engineering know-how? Meanwhile, Creena's attempt to return to Mira III for help is foiled when the planet where she expects to find starship passage not only can't help, but confiscates their ship. Will she remain trapped forever on an alien world pursued by mysterious and hostile forces?

• A Psilent Place Below (Vol. III) Taking refuge in Cyraria's network of caverns to survive Opposition, Dirck and his mother share a cryptic dream that promises death or worse for his imprisoned father. Will the daring and potentially lethal rescue Dirck and his friend, Win, fabricate succeed? If not, Laren will be lost forever. The political turmoil increases as the Integrator pursues planetary domination through increasingly devious means. The formation of a group to fight the hostilities delivers heavy consequences while additional threats at a more personal level arise in the form of cultural clashes between Mira III and Esheron. Creena's return partially reunites the family at last, but ongoing disagreements with her brother distract them from issues with even more dire consequences.

• Refractions of Frozen Time (Vol. IV) Creena and her little brother, Deven, believe the cavern's crystals can reunite their family at last, including bringing back their father who's on a prison ship heading for permanent exile. Before she can unlock their secrets, however, Integrator forces find their underground hideout, forcing a harrowing escape loaded with unexpected consequences. The lonely days that follow change Dirck forever while also revealing what drives the crystals' ability to manipulate time. Back on Cyraria, Laren's long-time nemesis, Augustus Troy, gains more power than ever before plus acquires a weapon capable of destroying anyone opposed to his despotic goals.

• Do the Brightstars have what it takes to survive their final confrontation with the Integrator and his evil proponents? Or will the family’s longed-for reunion take place in another dimension of time and space? Find out in this suspense-laden conclusion to the Star Trails Tetralogy.
