Journey The Only Survivors

The worldwide disappearance of all living creatures, after the catastrophic storm, brings Kyara to the brink of despair as she and her siblings go on a miraculous journey through time.
Kyara and her three siblings seem to wake up to a normal life, but what is normal can never be normal again after that night's storm, and everyone except the four kids disappear. When Kyara finds a time machine, disguised in a cell phone, they travel to the time when Jesus is born, in hope that they can find help from Him. But in each time after, they not only become vulnerable, but they also almost give up hope; for they lose the phone in every era they visit. While they journey through time, they learn about history, and how they can change it; they learn about faith, and how they can strengthen it;
and they also learn about love, and how they can protect it.
