Book 35

STARFLEET CORPS OF ENGINEERS
What begins as a simple investigation of a peculiar subspace signal leads to an errand of mercy, as the da Vinci responds to a distress call -- from the edge of a black hole! Hundreds of years ago, the Resaurians placed a station near the event horizon, forever teetering on the edge of the abyss, and now the S.C.E. must find a way to rescue them.
But the black hole, known as "the Demon," contains centuries-old secrets that the Resaurians will kill to protect -- and both the U.S.S. da Vinci and the station may be sacrificed to the Demon in order to preserve those secrets!

STARFLEET CORPS OF ENGINEERS
Over the years, the S.C.E. team on the U.S.S. da Vinci has solved innumerable problems, and escaped from numerous deathtraps, from the ravages of interspace to the gas giant of Galvan VI. Now, they must enter the outer reaches of a deadly black hole known as "the Demon" in order to rescue an away team from a hidden Resaurian prison teetering on the edge of the singularity.
But the Resaurians will do everything they can to preserve their secrets, and keep the da Vinci from getting out of the Demon alive!
