Savitar

The Solar System's two hundred twenty-million-year journey around the edge of the milky way was bringing it back to an encounter that had previously wiped out the Martian civilization.
This time the Earth was in the cross hairs.
Zackary Milton, with a PhD in Astronomical History and his professor now his partner Dr. Craig Garrity discover a small blackhole that will interact with the Solar system.
Zack envisions a way to capture and move it out of Earths path.
Craig's close relationship to the newly elected US president gets the program to protect the planet launched and gets Zack put in charge of the effort to capture and move the black hole.
The effort is globally supported but various factions want control of the gigantic space going vessel named by Zack as Savitar.
An assassination attempt is made on Zack while as he prepares to get the Savitar on its journey. He is saved by his most loyal personal guard, Janet. She has sworn that she will keep him safe.
The Savitar and its crew of four thousand depart earth. They become aware that their path will take them too close to the Moon and will most likely tear their vessel apart.
Zack and his crew overcome that first threat and become sensitive to other potential ways that the Savitar may be sabotaged.
They isolate the Savitar from any computer connection with Earth and take complete internal control.
Subsequent events, including a second assassination attempt of Zack causes a complete reassessment of all control systems.
Each barrier is overcome with the teamwork of the crew.
The Savitar continues to be built as it travels on its multi-year voyage out to intercept and capture the black hole.
How the Savitar captures and contains the black hole is significantly changed from the original plans made on Earth. This change exposes and circumvents a number of preplanned sabotage actions by various parties on earth.
The economic powers on Earth have all designed new, fast spaceships and plan to take control of the Savitar. Craig still on Earth has convinced the US president that Zack is prepared and has the Savitar capable to defend itself against all threats. The US sends out a contingent with only thirty commandos and a group of professionals renowned in their fields of expertise.
Zack prepares for the confrontation with the approaching space vessels in a manner that he hopes will prevent a shooting confrontation. He is set up to do so if necessary and feels certain his defense system is superior to anything he will face.
The approach and the friendly demonstration of the Savitar's superior capability allows the Savitar to set itself up as the neutral Switzerland of space.
The environment on the Savitar takes on a new and positive way of life.
Janet, his loyal protector, and his true soul mate soul mate get married on the Savitar, on a simulated Hawaiian beach where she had always wanted her wedding to be.
