Very nicely written book which keeps you involved as the plot unfold and along with the main person you also set to know where exactly he is and why is he there
Really like backstory in each of the chapters that makes it more interesting
Kudos to writer when trying to introduce alien specifies and ways to communicate and how to fight same enemy
On some pages, it goes quite technical in Physics which require double read but brilliantly written
Though little bit of too much heroism and little anti climax for me in the last chapter but it’s a real woth read and the way it’s written you yourself visualise that you are actually Dr Grace and hope for him to succeed
